32bit HVM PV drivers on 64bit hypervisor
Hi Steven,
I onced played with your PV-on-HVM driver before it is checked in into
unstable, I remember at that time, there is a XENFEAT_64bit_shared_info
flag to handle situation of 32bit guest on 64bit hypervisor, at least
vnif works fine with it.
Later, when the code is checked in, this flag is gone. At first I though
this was an effort to make hypervisor more transparent to HVM guest, but

Bug#554805: xen-utils-3.2-1: ioemu routed networking on HVM guests fails
Package: xen-utils-3.2-1
Version: 3.2.1-2
Severity: normal
Under this Xen setup, (Linux) HVM guests fail to have network active
when
running with *routed* networking, as some hosting providers require (in
my
case, OVH).
In this scenario:
* the host is a described below
* the guest runs as HVM.
* the guest runs exclusively with ioemu; virtual network drivers are
not
available (vanilla lenny

a domain VTx with the VNIF does hang.
Hi all, my name is Hirofumi Tsujimura.
We are porting and testing a PV-on-HVM in the IPF.
This is a first time to send mail.
I probably found the problem when I tested the VNIF.
My operation for the test is following.
1. create a domain VTx and attach the VNIF in it.
2. create a domain U.
3. send a packet to the domain VTx from the domain U with ping
command.
Then, the domain VTx

stubdom questions
samuel,
I have a try with HVM stubdomain on r17062, but failed to make on 32b platform.
Attached patch can fix it, but don''t know if okay.
After installation, I failed to start stubdom. So I created it manually and got
following debug mesg(both HVMdomain and stubdom are created)
Can you give some lights on following questions:
1. I use default vnclisten. Does it matter?
2. Seems qemu

Linux PV Drivers - VBD device not loading - Cannot get Major 3/22 for ide
I am trying to get PV drivers running on both Centos 5.1 and Centos 5.3
HVMs, my DomU is Centos 5.2 with Xen 3.31. For 5.1 I install the
kmod-xenpv RPM but for 5.3 the drivers seem to be built-in.
For the network drivers to work I had to unload the Realtek NIC driver
and renamed its .ko files to stop it loading. Adding the Xen-Vnif alias
to modprobe.conf then got the PV NICs working nicely (Much

[PATCH] qemu-dm: add command to flush buffer cache
Add support for a xenstore dm command to flush qemu''s buffer cache.
qemu will just keep mapping pages and not release them, which causes problems
for the memory pager (since the page is mapped, it won''t get paged out). When
the pager has trouble finding a page to page out, it asks qemu to flush its
buffer, which releases all the page mappings. This makes it possible to find

[PATCH] Fix request_module/modprobe deadlock in netfront accelerator
There would seem to be a potential deadlock in the netfront accelerator
plugin support. When the configured accelerator changes in xenstore,
netfront tries to load the new plugin using request_module(). It does
this from a workqueue work item. request_module() will invoke modprobe
which in some circumstances (I''m not sure exactly what - I''ve not
managed to reproduce it myself)

[PATCH][HVM] add mmio decoder 0x38 and some cleanup
PCmark2005 running in Windows XP is known to need this mmio decoder.
This patch also fixes some inconsistencies, the comments of mmio decoder
use AT&T ordering for operands, but the syntax looks like Intel asm.
This leads to much confusion.

Bug#554805: patch to enable routed networking in HVM+ioemu
tag 554805 + patch
thanks
The problem to solve is that qemu-ifup assumes the world is always
bridged, and vif-routed does not know of the concept of TAP devices, and
even if it did, it has at this point no way to get at qemu's TAP device
anyway.
The following set of patches help run in the ioemu-HVM situation:

[PATCH][VNC Auth] Fix qemu-dm becomes defunct when rebooting hvm domain
Hi,
Sorry, I should not have removed infomation on xend.
image.py, line 399, in configVNC
config.remove([''vncpasswd'', vncpasswd_vmconfig])
When vncpasswd is removed, qemu-dm cannot be started in reboot of hvm domain.
Because necessary information disappears.
It cannot be helped though information in config list remains in xenstore.
This patch corrects above.

black screen when booting ubuntu cd in hvm

i have a problem to boot an Ubuntu CD in a hvm-enabled machine. I

When i change the line cdrom= to some other CD (grml Live CD,
Windows CD, other ones) it runs fine. But any Ubuntu CD (kubuntu

Paravirtualised drivers for fully virtualised domains
(The list appears to have eaten my previous attempt to send this.
Apologies if you receive multiple copies.)
The attached patches allow you to use paravirtualised network and
block interfaces from fully virtualised domains, based on Intel''s
patches from a few months ago. These are significantly faster than
the equivalent ioemu devices, sometimes by more than an order of
magnitude.

[patch, rfc] put IP addresses into xenstore
Hi,
$subject says pretty much all, this patch updates netfront and makes it
store the network addresses of the interfaces in xenstore, so it''s much
easier to figure what IP some virtual machine has and (for example) ssh
into it.
comments?

problems with xen and hvm
Dear xen-users.
First of all, I''m not a linux-guru and a beginner with xen and
completly new in this mailinglist.
I''ve installed Xen on debian 6 and I was successful creating two
machines: one for tests and "fogserver" (to test speed of writing
computer images), both para-virtualisations.
