Hello,

at the moment we are investigating stalls of Windows XP VMs during
live migration. Our environment consists of:
=20
- FC20 hypervisor nodes=20
- qemu 1.6.2
- OVirt 3.4.1
- Guest: Windows XP SP2
- VM Disks: Virtio & IDE tested
- SPICE / VNC: both tested
- Balloon: With & without tested
- Cluster compatibility: 3.4 - CPU Nehalem
=20
After 2-10 live migrations the Windows XP guest is no longer =
responsive.
=20
First of all we thougth that it might be related to SPICE because we =
were
no longer able to logon to the console. So we installed XP telnet =
server in=20
the VM but that showed a similar behaviour:
=20
- The telnet welcome dialogue is always available (network seems ok)
- Sometime after a live migration if you enter the password the =
telnet=20
gives no response.
In parallel the SPICE console allows to move open windows. But as soon
as one clicks on the start the menu the system gives no response.
=20
Even after updating to qemu 2.0 with virt-preview respositories the
behaviour stays the same. Looks like the system cannot access
This really seems more either SPICE or QEMU related=85.
You can isolate the behavior to that single VM? Or single OS type(others =
work ok)? or it's happening for any other VM randomly?
Thanks,
michal
=20
Any ideas?
