xen 4.1.1 + 3.0.0-rc5 dom0 + blktap2
Hi,
I''m currently trying xen 4.1.1 with the 3.0.0-rc5 (heard that it now
contains the xen code to run as front or back xen domain).
Everything seems to run fine, except that I am trying since a few hours
to mount a .vhd file in the dom0.
What I tried so far:
to create a blank vhd file (this is working):
host# vhd-util create -n /storage/test.vhd -s 20G
Then i try to mount the file

blkback global resources
All the resources allocated based on xen_blkif_reqs are global in
blkback. While (without having measured anything) I think that this
is bad from a QoS perspective (not the least implied from a warning
issued by Citrix''es multi-page-ring patches:
if (blkif_reqs < BLK_RING_SIZE(order))

Creating a vm with a non-existent /dev/mapper/ tap2 device effectively hangs dom0 system
Have an interesting one here, originally found on xen 4.1.0 but just
upgraded to xen 4.1.1 and it''s still here.
Creating a VM with a tap2 device pointed at /dev/mapper/something, when
that device doesn''t exist, causes the tapdisk2 process to go into D mode
and also manages to take out any process that queries it.
For example, I have /dev/mapper/nathanxenuk1 as a valid disk

qemu VS tapdisk2 VS blkback benchmarks
Hi all,
as promised I run some simple benchmarks using tapdisk2 and the new qemu
as disk backends.
If you are in a hurry skip to the last section to see the test results.
SOFTWARE REQUIREMENTS
---------------------
In order to reproduce these results you need to use the new qemu with
linux aio and O_DIRECT as disk backend:
- apply the libxl patches that Anthony sent to the list a little while

[PATCH 0 of 4] aio event fd support to blktap2
Get blktap2 running on pvops.
This mainly adds eventfd support to the userland code. Based on some
prior cleanup to tapdisk-queue and the server object. We had most of
that in XenServer for a while, so I kept it stacked.
1. Clean up IPC and AIO init in tapdisk-server.
[I think tapdisk-ipc in blktap2 is basically obsolete.
Pending a later patch to remove it?]
2. Split tapdisk-queue into

Re: Re: XAPI on debian - sr-create issue
You''re right scout the last line. Out looks like xapi is waiting on tapdisk to plug a key into xenstore. Perhaps a udev rule problem? Perhaps someone who knows more about tapdisk than I well be able to diagnose this tomorrow.

blktapctrl not running
Hi,
I am running XEN 4.1 on Debian 6 and I cannot find blktapctrl process
running. xend is started. I installed XEN from 4.1 source following
instructions here:

Should there be a blktapctrl process running in this version?
The problem I have encountered is that I can create a domain on a raw disk

RFH: loopback & blktap(2) and CDROM
Hello,
I''m currently trying to understand some problems I had in the past with mixing
look-back with blktap(2) for HV and PV domains. I''m stuck reading the source
code, so I''d like to get some help from the list. Interrupt me if I got
something fundamentally wrong in my understanding so far:

What is the state of blktap2?
I''m currently working on moving storage services into their own domain
and I''ve been looking at blktap2. I''ve been trying to get an image
mounted with blktap2 and for some odd reason and tapdisk2 keeps hanging
instead of quitting at the end. I haven''t removed any of the storage
startup code at this point so everything should be as it normally is in
xen-unstable.

Errors of doing "make install-tools" with xen-4.2-unstable?
Hi,
When I do the "make install-tools" with xen-4.2-unstable, there are some
errors about "warn_unused_result".
Is it the error in code or the error in the compiling environment? Thank
you so much.

tap:aio not working...
I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

[PATCH] Blktap: Userspace file-based image support. (RFC)
Attached to this email is a patch containing the (new and improved)
blktap Linux driver and associated userspace tools for Xen. In
addition to being more flavourful, containing half the fat, and
removing stains twice as well as the old driver, this stuff adds a
userspace block backend and let you use raw (without loopback), qcow,
and vmdk-based image files for your domUs. There''s also a

detecting a ''block-configure'' via xenbus
How should I be detecting a block-configure operation done in Dom0 in a
HVM DomU?
Under Debian Lenny''s Xen 3.2.1, when I execute such a command, Dom0
writes to the backend values ''params'' and ''type'', twice, but doesn''t
update the ''sectors'' value to match the new device, or initiate a state
change. Given that, the best I can
