[libvirt-users] Host and Guest UUID ?
Hi, Are there some kind of UUIDs for Host and Guest ? If yes , how may I retrieve them programmatically ? My goal is to trace GUEST migrations. Thx for help. Regards, J.P.

Guests have a UUID, it's part of the XML description, e.g., $ virsh dumpxml myguest | head -3 <domain type='kvm' id='10'> <name>myguest</name> <uuid>b392ddf3-ed7a-4a4d-ba22-159d87bd601d</uuid> You can get this using the virDomainGetUUID() api call. Hosts have a UUID that is visible via the 'capabilities' information: $ virsh capabilities | head -4 <capabilities> <host> <uuid>65bf8701-5216-11cb-baa9-9ee038331cdf</uuid> This information is available via the virConnectGetCapabilities() api call. -- Lars Kellogg-Stedman <lars@redhat.com> | larsks @ {freenode,twitter,github} Cloud Engineering / OpenStack | http://blog.oddbit.com/
