[Pkg-xen-devel] Bug#648670: xm was unable determine an actual domU state under some conditions
Package: xen-utils-4.1 Version: 4.1.1-3 I have an HVM domU which was created with xen-utils-4.0 (and Xen 4.0 hypervisor of course). Recently I've upgraded to Xen 4.1 and xen-utils-4.1, but after a reboot I was unable to do anything with it: "xm start" caused "Domain is already running" error, while "xm shutdown" simply hadn't printed any error messages, only "Error:", "xm destroy" did nothing without any output. In "xm list" output the domU had no ID and state values just like it wasn't started. ==# xm shutdown test1 Error: Usage: xm shutdown <Domain> [-waRH] Shutdown a domain. == ==# xm reset test Error: Domain 'test1' is not started Usage: xm reset <Domain> == ==# xm start test1 Error: Domain is already running Usage: xm start <DomainName> == The only reasonable message was in xend.log, appears when I tried to shutdown the domU: ==DEBUG (XendDomainInfo:524) XendDomainInfo.shutdown(poweroff) ERROR (xmlrpclib2:181) Internal error handling xend.domain.shutdown Traceback (most recent call last): File "/usr/lib/xen-4.1/bin/../lib/python/xen/util/xmlrpclib2.py", line 134, in _marshaled_dispatch response = self._dispatch(method, params) File "/usr/lib/python2.7/SimpleXMLRPCServer.py", line 420, in _dispatch return func(*params) File "<string>", line 1, in <lambda> File "/usr/lib/xen-4.1/bin/../lib/python/xen/xend/server/XMLRPCServer.py", line 56, in dispatch return getattr(info, fn)(*args) File "/usr/lib/xen-4.1/bin/../lib/python/xen/xend/XendDomainInfo.py", line 533, in shutdown self.storeDom("control/shutdown", reason) File "/usr/lib/xen-4.1/bin/../lib/python/xen/xend/XendDomainInfo.py", line 1705, in storeDom return xstransact.Store(self.dompath, *args) File "/usr/lib/xen-4.1/bin/../lib/python/xen/xend/xenstore/xstransact.py", line 347, in Store complete(path, lambda t: t.store(*args)) File "/usr/lib/xen-4.1/bin/../lib/python/xen/xend/xenstore/xstransact.py", line 361, in complete t = xstransact(path) File "/usr/lib/xen-4.1/bin/../lib/python/xen/xend/xenstore/xstransact.py", line 27, in __init__ assert path is not None AssertionError == I was able to remove the failed domU only by removing the appropriate directory with config.sxp from /var/lib/xend/domains.
