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 john changeset: 15142:78389dbb08bb user: Steven Hand <steven@xxxxxxxxxxxxx> date: Fri Sep 14 16:33:34 2007 +0100 files: tools/python/xen/xend/XendDomainInfo.py 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.
