@ Serge
I write down the process I have tried to solve this issue...
First the nova-compute.log show an ERROR as follow...
2013-05-21 16:19:11.230 ERROR nova.compute.manager [req-0e30e53b-

None:raise libvirtError(\'virDomainDefineXML() failed\', conn=self)\n',
"libvirtError: internal error no supported architecture for os type
'hvm'\n"]
Then I check the "/usr/lib/python2.7/dist-packages/libvirt.py" at line
2760, it is a function in class virConnect
def defineXML(self, xml):
ret = libvirtmod.virDomainDefineXML(self._o, xml)
if ret is None:raise libvirtError('virDomainDefineXML() failed',
conn=self)
__tmp = virDomain(self,_obj=ret)
return __tmp
To output the xml I add some code as follow and restart nova-compute
service
def defineXML(self, xml):
# save xml files to a temporary location
import __builtin__ as bu
f = bu.open("/tmp/libvirt.xml", "w")
f.write(xml) # Write a string to a file
f.close()
ret = libvirtmod.virDomainDefineXML(self._o, xml)
if ret is None:raise libvirtError('virDomainDefineXML() failed',
conn=self)
__tmp = virDomain(self,_obj=ret)
return __tmp
When re-create a vm use OpenStack Dashboard, I got the /tmp/libvirt.xml
as follow

hvm
One can find the first line () that it still specify to use
KVM rather than Qemu, though I already specify "libvirt_type=qemu" in
nova.conf. According to #3 @Jamie's post, I found two possible way to solve it.
1. change the first line to
2. change the line 16 to hvm
For testing, I have added some code in /usr/lib/python2.7/dist-
packages/libvirt.py to change the xml (ex. xml =
xml.replace('type="kvm"', 'type="qemu"',1)). Both method works fine.
So I still do not sure is it the bug of libvirt of Nova?
