Hi,
is there any known issue when migrating a WinXP SP3 guest with qemu-kvm 0.13.0
or qemu-kvm-0.12.5?
If I migrate such a guest with a Realtek rtl8139 Network Device and an USB
Mouse Tablet
after migration the USB Tablet doesn't work any more and network stalls. I have
seen the mouse
moving a few seconds after migration and that stop moving.
usb devices simply don't have migration support. The 0.14 release will
add that for usb hid devices and the usb hub.
Whenever the devices work after migration depends on how the guest os
handles usb errors. Recent linux kernels just reset+reinitialize hid
devices which fail, log a message about it and go on without a hitch.
Other guests might be more sensitive, so this could be it, but maybe it
isn't.
No idea on the rtl issue.
cheers,
Gerd
