Problem with tap:aio
Hi all
I was reading through Xen 3 user manual and saw this tap:aio should be used
instead of loopback...
Then I came to do that, but I can get it working with replacing `file'' URI''s
with `tap:aio''.
My OS: Debian Lenny 2.6.26-2-xen-amd64
DomU Xen configuration file:
kernel = ''/boot/vmlinuz-2.6.26-2-xen-amd64''

GPL PV TAP cow incompatible?
Hi
Is it true that the GPLPV drivers is incompatible with QCOW images?
The Windows DomU works fine with raw standard "file:/" images, and
paravirtualized Linux DomU works fine with QCOW and raw images.
If i use QCOW images with my Windows DomU''s i get a stop error:
0x00000007b (inaccessible boot device).
It looks like the blkback.3.hda process, that normally starts with

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.

tap:aio support Xen Debian lenny
Hello,
I installed Xen 3.2.1 on Debian Lenny from packages. Then created image
files with 'xen-create-image --size=2Gb --swap=128Mb --dhcp --dir=/xen

following configuration file:

ramdisk = "/boot/initrd.img-2.6.26-1-xen-686"

Hello.
I''m trying to get the lastest GPLPV binary (rev 238) working on an

BLKTAPCTRL[2375]: blktapctrl_linux.c:86: blktap0 open failed
I''m getting this message (subject line) in daemon.log every time I
start or restart xend. I''m not sure if this is related to the fact
that I cannot boot up my Windows domU from a VHD file. The Windows
domU was working fine with Xen 4.0.0 (with 2.6.32.14 dom0 kernel).
When I upgraded to Xen 4.0.1-rc4 (with 2.6.32.16 dom0 kernel), I can
no long boot the Windows domU from VHD. The

Tap:aio not working in current unstable?
Maybe it''s something I''m doing wrong, but I have a 15gb image that I use
with disk = [ "tap:aio:/root/images/vista32.img,hda,w" ]
It was working fine on Friday, but today it failed to boot with an error
message.
The same works fine when I replace "tap:aio:" with "file:". It seems
like qemu-dm tries to open the file with the "aio:" still

Xen 3.3.1 + Windows 2008 x64 + GPLPV 0.9.12-pre13 = corruption?
Hi James,
I''m testing GPLPV 0.9.12-pre13 on Windows 2008 x64, and found some
interesting results :
- The drivers are NOT signed, even though I''ve install certs. Had to
use F8 on boot.
- both QEMU and Xen block device are active, which usually means
corruption is coming. Is this a known issue?

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

Release 0.9.5 of GPL PV Drivers for Windows
I''ve just made my first ever attempt at an Nullsoft installer, so if you
want to try it download "Xen PV Drivers 0.9.5.exe" from
http://www.meadowcourt.org/downloads/
The installer should detect the version of windows you are running and
install the drivers. At the moment you''ll need to install the shutdown
monitor service manually, but you can do that from the start

Xen HVM and tap:aio
Hello,
I'm wondering if anyone out there is doing tap:aio disk devices on a Xen HVM
vm with any success. Please let me know if you are, and perhaps your
version info and a config file snippet.
I've posted this to the xen-users list, and what I'm trying to do seems to
be correct, works on Ubuntu, Debian, and XenSource; but it doesn't work on
CentOS.

Bug#517007: xen-utils-3.2-1: tap:aio on disk image files is not usable
Package: xen-utils-3.2-1
Version: 3.2.1-2
Severity: important
/usr/lib/xen-3.2-1/bin/blktapctrl
searches for tapdisk executable in /usr/bin
while is in /usr/lib/xen-3.2-1/bin
this makes tap:aio unusable
I've linked to /usr/bin and everything went fine
perhaps the idea is to patch sources to pick
executable from the right directory
