Seems that this is due to:

https://bugzilla.redhat.com/show_bug.cgi?id=1446147

I will check If i can find newer guest agents.

Hi all,

I am running a 3 node ovirt 4.1 selft hosted setup.

I have consistently observed that windows 10 VMs with SPICE console fail to live migrate. Other VMs (windows server 2016) do migrate normally.

VDSM log indicates:

internal error: unable to execute QEMU command 'migrate': qxl: guest bug: command not in ram bar (migration:287)
2018-02-18 11:41:59,586+0000 ERROR (migsrc/2cf3a254) [virt.vm] (vmId='2cf3a254-8450-44cf-b023-e0a49827dac0') Failed to migrate (migration:429)
    if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self)
libvirtError: internal error: unable to execute QEMU command 'migrate': qxl: guest bug: command not in ram bar

Seems as a guest agent bug for Windows 10? Is there any fix?

Thanx,

Alex
