[libvirt] [PATCH] virVMXParseDisk: Recognize scsi-passthru
by Michal Privoznik
https://bugzilla.redhat.com/show_bug.cgi?id=1172544
So, imagine you have this config:
scsi0:1.present = "TRUE"
scsi0:1.deviceType = "scsi-passthru"
scsi0:1.fileName = "/vmfs/devices/cdrom/mpx.vmhba32:C0:T0:L0"
scsi0:1.allowGuestConnectionControl = "FALSE"
So far, libvirt does not recognize this pattern and fails. What
if we produce the following XML to it?
<disk type='block' device='disk'>
<source dev='/vmfs/devices/cdrom/mpx.vmhba32:C0:T0:L0'/>
<target dev='sdb' bus='scsi'/>
<address type='drive' controller='0' bus='0' target='0' unit='1'/>
</disk>

[libvirt] Missing CPU vendor in capabilities in 1.2.18+
by Guido Günther
Hi,
We have a report in Debian[1] where after a update from 1.2.16 to 1.2.18
VMs on a Intel i5 CPU fail to start due to libvirt not being able to
match the CPU vendor:
# virsh start sid
error: Failed to start domain sid
error: unsupported configuration: guest and host CPU are not compatible: host CPU vendor does not match required CPU vendor Intel
The root cause seems to be that the <vendor> element is missing from the
hosts capabilities. While I have:
$ virsh capabilities | xpath -q -e //host/cpu/vendor
<vendor>Intel</vendor>
on my Intel box the reporters machine with a Core i5 the <vendor> element is just
empty. Any idea what could have triggered this? This is still broken in
1.2.19-rc1. The bug has more details and logs attached. Any pointers
would be welcome since I don't have access to such a machine atm to step
through src/cpu/cpu_x86.c.
Cheers,
-- Guido
