With 3.1.2rc2:
bash-3.00# xm destroy sxc15
bash-3.00# xm list
Name ID Mem VCPUs State Time(s)
Domain-0 0 6596 4 r----- 202.7
sxc13 1024 1 52.0
sxc15 6 1024 1 ------ 0.0
It's the below changeset - no code to reset the domid exists any more.
It seems suboptimal to me? Shouldn't refreshShutdown (or somewhere,
anyway) remove domid?
I noticed this whilst having another, more serious problem: sometimes,
domains are never released, with a page still referenced (presumably?):
>>> xc.domain_getinfo(21, 1)
[{'paused': 0, 'cpu_time': 4895498373L, 'ssidref': 0, 'hvm': 0,
'shutdown_reason': 0, 'dying': 1, 'mem_kb': 4L, 'domid': 22,
'max_vcpu_id': 0, 'crashed': 0, 'running': 0, 'maxmem_kb': 1048576L,
'shutdown': 0, 'online_vcpus': 1, 'handle': [75, 158, 234, 68, 113, 241,
195, 238, 113, 125, 31, 198, 154, 74, 44, 188], 'blocked': 1}]
None of the user-space daemons seem to be the culprit. I'm still trying
to find out why xen thinks a page is still held. Note that this domain
is still using flip instead of copy - I know that's not the default,
could a bug there have crept in?
cheers

description:
This patch fixes the issue with waiting for devices to disconnect during the end
stage of migration in Xend. The problem was cause by a deletion of the VM domain
ID which is used by testDevicecompleComplete ->deviceIDs->backendRoot() to get
the virtual backend device path. The virtual backend device path is used to
check if a device still exists in xenstore.
