Description Richard W.M. Jones 2018-07-05 07:48:30 UTC

Description:

VMware supports genid in its vmx metadata files, eg:

vm.genid = "7344585841658099715"
vm.genidX = "-8483171368186442967"

However the <genid> tag does not appear when dumping the XML of this guest>

# virsh -c vpx://root@xx/data/10.73.72.61/?no_verify=1 dumpxml esx6.0-win2012r2-x86_64 
Enter root's password for xx: 
<domain type='vmware' xmlns:vmware='http://libvirt.org/schemas/domain/vmware/1.0'>
  <name>esx6.0-win2012r2-x86_64</name>
  <uuid>564d5c84-172a-0ecd-05c9-14003ce70ae3</uuid>
[etc]

We expect to see <genid> here, as described here:

https://libvirt.org/formatdomain.html#elementsMetadata

Comment 2 Daniel Berrangé 2018-07-05 07:59:59 UTC

Hmm, genid should be a UUID, which means 16 unsigned bytes.  I guess vm.genid and vm.genidX are 8 byte signed integers which are supposed to be combined to form the full 16 byte UUID.

Hopefully these links will help:
