[libvirt-users] Error Attaching Seventh VirtIO-SCSI Device to Guest
by McEvoy, James
I have run into a problem attempting to attach the seventh virtio-scsi device to a RHEL 6.4 Guest from a RHEL 6.4 host running libvirt version 0.10.2-18.
I have a guest that is running RHEL6.4 where I can attach disks sda(boot), sdb, sdc, sdd, sde and sdf but when I try to attach sdg the virsh attach-disk command fails with the error:
error: Failed to attach disk
error: internal error Unable to determine model for scsi controller
I logged Bug 996327 on this issue including an attached script to repro the bug but there has been no activity on that bug so far.
This is the results when attaching virtio-scsi disks in a loop. Sdf is attached but sdg fails.
virsh attach-disk --domain UEM004n1 --source /dev/GuestVols/UEM004-5 --target sdf --cache none --type disk --config --wwn 1fc7058865439717 --serial c7d11fc7058865439717 --shareable
Disk attached successfully
Vol UEM004-6 created
virsh attach-disk --domain UEM004n1 --source /dev/GuestVols/UEM004-6 --target sdg --cache none --type disk --config --wwn 4d3ddb9d15b05e7e --serial 62fd4d3ddb9d15b05e7e --shareable
error: Failed to attach disk
error: internal error Unable to determine model for scsi controller
The script to create and attach LVM volumes using virtio-scsi is available here:
https://bugzilla.redhat.com/attachment.cgi?id=785925
Has anyone else run into this... I had the understanding that each virtio-controller could support 4K devices.

[libvirt-users] Is virsh supposed to work on Windows?
by Fernando Lozano
Hi there,
Sorry for the cross-post, but I seeked help on this issue before on
those lists, but nobody answered. :-(
I'm trying to use virsh and virt-viewer on Windows. I'm running the
latest binaries from http://spice-space.org/download.html, that is,
virt-viewer-x64-0.5.7.msi on a Windows 7 64-bits computer.
So far I got remote-viewer.exe to work, after some pain. But have no
sucess using virt-viewer.exe and virsh.exe. Are they supposed to work,
or am I loosing my time?
I know the kvm host setup (a CentOS 6.3 machine) is fine, because I can
connect using virsh from other CentOS and RHEL machines. I'm using TLS
to secure connenctions to libvirtd, without client certs.
I had a litthe trouble finding where to put certificate files on the
windows machine, but using Sysinternals ProcessMonitor I found they have
to be on the obvious path:
C:\usr\x86_64-w64-mingw32\sys-root\mingw\etc\pki{CA,libvirt}
Even then virsh can't connect:
virsh # connect qemu://kvmhost/system
error: Failed to connect to the hypervisor
error: Unable to set close-on-exec flag: Success
ProcessMonitor "strace" doesn't help me find what went wrong. I'm sure
I'm using the same *.pem files that works for Linux clients. It looks
like virsh is opening and reading those files ok. ProccessMonitor shows
a TCP connect and a TCP Disconnect events to the correct IP and port,
both resulting SUCCESS.
Any ideas? What can I do to debug virsh on Windows and find why it isn't
connecting to libvirt on CentOS? I tried -d and -l on Windows and Linux
but can't find where the debug logs are saved.
If you want, I can send ProcessMonitor captured events.
For Red Hat folks out there: I need this working so I can get approval
to buy subscriptions, The idea is production hosts will be RHEL. :-) If
not, my boss may end up buying XenServer ;-)

[libvirt-users] Compiling libvirt for Xenserver 6.2
by Faisal Ali
Hi,
I am trying to compile libvirt-1.1.2 for Xenserver 6.2 using there DDK VM, however, it keeps giving error saying that it needs xenstore.h header file. However, I think Xenserver 6.2 is using older xs.h header file. Here is the excerpt of the beginning and end of the configure command
./configure
.
.
checking for xenstore.h... no
checking for xen/xen.h... yes
checking for xen/version.h... yes
checking for xen/dom0_ops.h... yes
checking for xen/sys/privcmd.h... no
checking for xen/linux/privcmd.h... no
configure: error: You must install the Xen development package to compile Xen driver with -lxenstore
How do compile with libvirt to look at xs.h file.
Thanks

[libvirt-users] windows guest network kept down automatically when several windows guest running in one KVM host,
by cochen
Hi all:
I have some kvm host(rhel 6.4, 2.6.32-358.0.1.el6.x86_64), I ran several windows guest on it(more than 10 guest on one host and the guest os are win7-32/win7-64/win2k8), but the guest network kept down automatically, lost package. I tried virtio drive and e1000 drive,but it didn't work. However, when I run cmd.exe ping some other subnet ip it worked.
The host and guest are connected by bridge.
Here is some configure infomation of my guest:

[libvirt-users] Customize UNIX socket permissions
by Jonathan Lebon
Hi,
I have a qemu domain which uses a virtio-serial port. On the
host, the unix socket is created in /var/lib/libvirt/qemu.
As non-root, I'd like to be able to communicate through this
unix socket.
The issue is that the socket is created as qemu:qemu with
permissions 755 (does this come from libvirt's umask?). Is
there any way to affect this permission from the domain's
XML definition file? Even if it has to be created as
qemu:qemu, having a permission of 775 would also be an
acceptable solution.
Thanks,
Jonathan
