[Users] ovirt fails to start vm on EL based nodes

[Brown, Chris (GE Healthcare)]

Is this something that could be turned into a documented "tunable" parameter for those that wish to use EL based distributions as nodes?

	Great debugging. 

	Sounds like the 'EmulatedMachine' (hope that's the right attr) in engine-config is configured for fedora based nodes. 

	 

	Would you mind openning a bug on this?

	Although I'm not sure oVirt supports RHEL completely. 

 

I don't think it's a bug; mean while, you can change 'EmulatedMachine' in vdc_options table from 'pc-0.14' to 'rhel6.2.0', restart Jboss, and it should work.

	The ovirt engine is failing to start virtual machines on EL based nodes.

	I think I have found the failure mode.

	The engine log shows:

	16:25:42.074: 10537: error : virNetClientProgramDispatchError:170 : internal error process exited while connecting to monitor: Supported machines are:

	pc         RHEL 6.2.0 PC (alias of rhel6.2.0)

	rhel6.2.0  RHEL 6.2.0 PC (default)

	rhel6.1.0  RHEL 6.1.0 PC

	rhel6.0.0  RHEL 6.0.0 PC

	rhel5.4.4  RHEL 5.4.4 PC

	rhel5.4.0  RHEL 5.4.0 PC

	 

	Thus output of qemu-kvm on the EL node is:

	[root at kvmsrv03 ~]# /usr/libexec/qemu-kvm -M ?

	Supported machines are:

	pc         RHEL 6.2.0 PC (alias of rhel6.2.0)

	rhel6.2.0  RHEL 6.2.0 PC (default)

	rhel6.1.0  RHEL 6.1.0 PC

	rhel5.4.4  RHEL 5.4.4 PC

	rhel5.4.0  RHEL 5.4.0 PC

	 

	And the output on a Fedora 16 node is:

	[root at vmdev ~]# qemu-kvm -M ?

	Supported machines are:

	pc         Standard PC (alias of pc-0.14)

	pc-0.14    Standard PC (default)

	fedora-13  Standard PC

	pc-0.13    Standard PC

	pc-0.12    Standard PC

	pc-0.11    Standard PC, qemu 0.11

	pc-0.10    Standard PC, qemu 0.10

	isapc      ISA-only PC

	 

	Thus it appears that ovirt-engine is passing an un-recognized "machine=" type when running on an EL node.
