avoid crash on HVM domain destroy with PCI passthrough
|
||
|
|
|
||
|
|
c/s bac6334b5 "move domain to cpupool0 before destroying it" introduced a
|
||
|
|
problem when destroying a HVM domain with PCI passthrough enabled. The
|
||
|
|
moving of the domain to cpupool0 includes moving the pirqs to the cpupool0
|
||
|
|
cpus, but the event channel infrastructure already is unusable for the
|
||
|
|
domain. So just avoid moving pirqs for dying domains.
