When rebooting a win7 domu with PCI pass-through enabled in Xen Hypervisor
4.1. I encountered the following error.
VmError: failed to assign device 01:00.0: maybe it has already been
assigned to other domain, or maybe it doesn't exist.
However, one could create the domain with no issues right after this error
appeared. Suggesting something in the reboot process is not waiting for all PCI
devices to detach.
At this time Iâm working around this issue by inserting a timer before the
VM gets created.
Iâve added (domain_reboot_timeout 10) to my xend-config.sxp and modified
some files as seen in attached. As I donât know python and I apologise for the
slackness of my approach.
At this time Iâm only passing through a Sound Card, USB Controller and an
ATI Graphics card. Perhaps this is hardware related. I have applied a patch for
the ATI card to work. However, this issue was present when the ATI card was not
listed in the config. As below you can see it reporting the same thing with the
USB Controller.
VmError: failed to assign device 00:1b.0: maybe it has already been
assigned to other domain, or maybe it doesn't exist.
Thanks,
