Hi Marco,

XCP 0.5 is primarily intended to be a bugfix release. However it does have 2 new
features:

1. CPU feature masking (via Intel FlexMigration and AMD-V Extended Migration)
   -- this allows you to (eg) "down-level" a new server to make it
look the same as an old server. The machines can then be joined to the same pool
and you can be sure that live migrations will work fine.

2. the ability to create and upload ISO images (provided the underlying SR is
itself writable)

Here's a short summary of the bugfixes, per area, since 0.1.1:

Toolstack:

fix a race in the Host_patch record update logic
Revert c/s 594:41501bb83b18 (session caching stuff)
Fix XenAPI performance degradation caused by RBAC
Support for likewise 5.3 error codes
Add first-class field for openvswitch distributed controller
Fix PIF_metrics glitch when xapi is restarted
Fix ballooning bug where a domain's maxmem gets out of sync in the no
ballooning required case (ie dynamic_min = dynamic_max)
Fix terrible error message when a 'rhlike' guest (eg CentOS) cannot be
installed because of a missing file
Read-only RBAC roles can call
pool.ha_compute_hypothetical_max_failures_to_tolerate
vswitch: the MAX address of the tagged PIF for VLAN fake-bridge
any PAM user should be able to log-in when external auth is disabled
robustify VBD unpause in the case when the device disappears
Make sure we can't VBD.plug while lvhd_stop_using_these_vdis is in progress
Make it possible to use new memory APIs on templates as well as VMs
Always allow dom0 to be ballooned even if other domUs cannot be ballooned
Resync Host_cpu tables with physical h/w on restart
Fix memory glitch when a domain is paused (eg while being resumed)
Fix a deadlock in the RRD code
Fix a glitch where xapi would set PV-drivers-up-to-date to false on restart
Extend VM.clone and VM.copy to work on snapshots and checkpoints
Add "Xen API SDK" template: using this to install from the main CD
should result in a simulator
Work around broken vendor kernels by forcing all PV guests to use slow resume
during checkpoint operations
Fix periodic backup of RRD data: broken by fork/exec daemon
Fix occasional HTTP request failure caused by failing to read all request
headers from an HTTP PUT
Improve the RRD behaviour when the system clock moves backwards
When importing VM metadata, if the VM was Running then the new state should be
Halted (not Running)
vswitch: fix bringing up VLAN PIFs
When deciding which host to forward a VDI.copy to (eg when installing a VM to a
different SR), take into account host liveness
SRIOV: on reboot, always hotplug PCI devices into guests in the order specified
in the (original) other-config key
Fix bug where 'xe pif-scan' could pick up non-physical interfaces such
as vif backends (!)
Avoid leaking a domain in the case where a storage backend fails during resume
Allow VCPU settings to be changed on a template
Allow the CLI to change a Host's name-description
Work around firewalls which kill idle TCP connections by inserting empty blocks
every 5s or so
Fix segfault in fork/exec daemon
Accept ISO8601 dates without a timezone, assume UTC (XMLRPC spec problems)

Dom0 kernel:

Fix deadlock in software raid by importing upstream fixes.
Enable CONFIG_NET_SCH_INGRESS
ensure gratuitous frames sent on bond link failure are truly benign
Allow large MTU to be configured on netback vif device from hotplug script.
pciback: fixes for SR-IOV passthrough to PV guests.
Fix iSCSI last_recv timestamp hijacking in iscsi_xmit.
Prevent iSCSI transport timeout checks from spinning.
Refresh Intel NIC drivers from http://e1000.sf.net
Do not restrict netback to the first 2k of each RX buffer.
Backport xenbus_watch_pathfmt which is used in place of xenbus_watch_path2 in
pvops kernels.
compile pciback in the kernel (not as a module)

xen (3.4.2):

EPT/PoD locking fix 
Backport upstream patch to support syslinux configuration files in pygrub.
add AES to the HVM CPUID whitelist.
Import upstream patch to improve pygrub compatibility with grub2.
Upgrade gPXE to 1.0.0
don't complain too loudly about mixed-CPU migrations.

Added patch to fix network booting from Bootix serverion
quieten per-cpu logging and increase dmesg buffer size.
import Intel changes to FlexMigration
trace possible incorrect use of SPIN_LOCK_UNLOCKED
With OOS enabled, check l1 and rewalk if it's changed just before
propagation.
improve support for grub2 and reiserfs/ext4
CA-40782: Sort out interactions between PoD and log-dirty on EPT.
pygrub: Fix Grub2 support for Ubuntu 10.04

storage plugins

Fix SAS dynamic device removal/addition behaviour
Fix race in waiting for LUNs to appear. 
if we fail to remove a devmapper node, leave the LV symlink
retry on failures during "dmsetup remove" (since most of those are
transient)
Run NFS slave callout before unlinking parent VHD.
Activate the dm-multipath node before calling vdi_attach
enable single snapshots (1 leaf instead of 2), which would have been needed for
online leaf-coalesce
Make VDI.introduce on LUN-per-VDI backends set managed=true on the  VDI.
Add Multi-IQN wildcard support to the iSCSI target discovery functionality.
fix a journal file race
use the BAT information to minimize the space requirements of coalesce
fix the space requirement calculation in vdi_snapshot
make vhd-util log errors to syslog (except for vhd-util scan).
log some diagnostic info when LV fails to get activated
fix the clone rollback call params
Ensure that root dev does not get re-probed when refreshing the SCSI host bus.
Report the correct number of iSCSI sessions when the MultiIQN wildcard is being
used.
don't trust LVM when it says a LV doesn't exist: still check if the
devmapper node and/or symlink do exist and delete them manually
Restore set_scheduler device name for multipathed nodes.
VM template should only be created when snapshotting via
vm-snapshot-with-quiesce.
zero out the footer area of the LV when rolling back inflates

Dave

I found third (on my count) bug:

If we set up VM memory limits like this (on shutdowned machine):

xe vm-memory-static-range-set max=1048MiB min=96MiB vm=test
xe vm-memory-dynamic-range-set max=1048MiB min=96MiB vm=test
xe vm-memory-target-set vm=nonballoon target=110MiB
... and start VM. We found it take about 96Mb of RAM.

And if we starts to change it with xe vm-memory-target-set command, we
can increase, but can not cut memory down until about 230Mb (from 500 to
300 - ok, from 300 to 150 - no).

I thinks this have some relation with code in in
drivers/xen/balloon/balloon.c:

static unsigned long minimum_target(void)
...
        if (max_pfn < MB2PAGES(128))
                min_pages = MB2PAGES(8) + (max_pfn >> 1);
        else if (max_pfn < MB2PAGES(512))
                min_pages = MB2PAGES(40) + (max_pfn >> 2);
        else if (max_pfn < MB2PAGES(2048))
                min_pages = MB2PAGES(104) + (max_pfn >> 3);
        else
                min_pages = MB2PAGES(296) + (max_pfn >> 5);
...

I think, those numbers are unreasonable (especially around 2Gb limit).

I never thought putting policy like that in the kernel driver was a good
idea. Its intention is to stop stupid users echoing unrealistic targets into
/proc/xen/balloon. Possibly these checks could be removed, made configurable
on the kernel command line, or only applied to target changes via /proc,
leaving updates via xenstore unchecked.

There''s a whole very unproductive argument around this as to whether
policy
belongs in a kernel (hard to change, but maybe knows more about the VM),
versus in a higher-level toolstack (easier to change, maybe knows less about
the VM); safety vs flexibility; blah blah blah.

Hi!

 The XCP have some kind of storage vmotion, like in VMWare?!
 If not, I believe that the librsync can help you guys in inplementing this!
 Today I''m doing this "storage vmotion" manually with rsync
and it works!

Cheers!

Could you double-check the md5 of the iso just in case?

I'm hoping to upload an RC2 RSN with at least two more fixes:
1. bug #1614: losing vcpu weight/cap settings after a migrate/resume
2. a workaround for pool.designate_new_master failing when xapi tries to save
large amounts of performance data

Cheers,
Dave

Hi Dave:

The md5 is right. I think the ISO has some problem.

Hi everyone,

The second release candidate of the Xen Cloud Platform (XCP) version 0.5 is now
available for testing from:

http://www.xen.org/products/cloud_source_0.5.html

The changes since the RC1 are:

* VCPU weight/cap/affinity are now preserved over VM migrate, resume
* CLI command ''xe get-vms-which-prevent-evacuation'' now
follows the usual CLI pattern and ''--minimal'' works as
expected
* Failure to manually change the pool master when there is a large amount of RRD
data has been fixed[1]
* pygrub now supports ext4 filesystems
... leading to ...
* experimental support for Ubuntu Lucid Lynx 10.04[2]

Please download and test! :)

[1] if there are a large number of RRD datasources (eg corresponding to a large
number of VLANs) then the RRD XML becomes large and serializing it will fail.
This failure nolonger causes the pool master transition to fail but it does
prevent the XML being saved to disk. Hopefully this will be fixed in the
unstable branch for the next release.

[2] thanks to Alex Zeffertt, David Markey and Ian Campbell for sorting this out.
Note that you should select the network install option if you are using a
console like OpenXenManager.

Cheers,
Dave

The changes since the RC2 are:
* it should now be possible to upgrade from previous RCs as well as 0.1*
* a template for 64-bit Ubuntu 10.04 now exists (previously only a 32-bit one
was present)
* experimental templates for 32-bit and 64-bit Debian Squeeze are included

Please download and test! :)

Cheers,
Dave

Is it possible to interrupt booting process of the Installation CD-ROM to force
text mode, rather than graphic mode? Looks like the graphic card of my machine
is not supported.

Tomorrow I''ll install XVP 0.5 on a IBM x3550 M2.
I''ll report to the list if I found something buggy.

I have a request (but this may not be the right way to ask)... Can we name
the .ISO file something other than main.iso? Without opening the ISO or
booting from it you can''t easily tell what it is or which version. It
would
be nice if the naming convention for the ISO was something like
XCP-base-0.5rc3.iso or something.

Greetings,

I am attempting to create a cloud demo and having problems building the
images. As time is of essence, if you have vanilla Xen images of openSUSE,
Debian, Ubuntu, Feudora, RedHat et al, to share, I would take them ,-)

Hi Jimmy,

On my Debian (lenny) hosts, I most of the time use xen-tools to create debian
domU''s/images, it should be able to do centos as well.

Does xen-tools support XenServer/XCP nowadays?

Hi Grant,

That’s a good idea. When we release 0.5 (imminent) I’ll make symlinks named
  XCP-base-0.5.iso{,.md5}
  XCP-ddk-0.5.iso{,.md5}
and link to those.

Cheers,
Dave

:-( Is it causing your console to get stuck permanently? The actual installer is
all in text mode.

I can concur. I was having major issues getting ubuntu 10.04 to install 
a pv domu on my centos dom0 with xen3.4.2 and xen4.0. I got a 
subscription to stacklet and within the hour I had a working image. They 
have all kinds of distros.

I see the enlarged image of the initial BIOS boot (like F2 for setup) there,
after loading Xen and dom0, and I don''t see the (Panda) picture. I
guess the display mode is changed when the picture is displayed? I have a Matrox
PCIe x1 on that machine. If I use a different graphic card, it installs fine.

I can install Ubuntu 10.04 server on the machine even with the Matrox card
because it completely stays in text mode. Probably we need an option to give up
the picture, although I''m not sure that''s the cause.

Thank you. This is *very* helpful when one has to keep multiple 
versions around. Nothing worse than using the wrong main.iso.

Might I make one more request?

sed ''s/main/XCP-base-0.5/'' XCP-base-0.5.iso.md5

Otherwise, an `md5sum -c` fails.
