-------------------------------------
Summary: libvirt get_domain_info fails to properly identify
vmhost's domains
Key: VCL-721
URL: https://issues.apache.org/jira/browse/VCL-721
Project: VCL
Issue Type: Bug
Components: vcld (backend)
Affects Versions: 2.3
Environment: Centos 6.2 (vm, hosted on vmhost which is ubuntu 12.04)
Reporter: Christopher Wolfe
During capture, when ascertaining domain names from virsh, libvirt.pm's
get_domain_info function incorrectly parses the output of "virsh list --all".
The regular expression to split the output line into id, name, status only
captures a single space between id and name, thus resulting in additional space
assigned to the name field. This extra space causes subsequent 'virsh dumpxml
"<name>"' command to produce an error as virsh interprets the space to be part
of the name, etc. The solution is to add a "+" in the regex after the
whitespace-capture. Also for good measure, I've trimmed leading and trailing
whitespace from $name after the capture.
I can't remember, off-hand, what the resulting CRITICAL error message ends up
being, but it's something along the lines of "XXXHOSTXXX does not correspond to
any defined virtual machine", or possibly "cannot determine the MAC address of
XXXHOSTXXX
