[libvirt] [PATCH 2/2] virsh-domain: Report errors on invalid --holdtime value for cmdSendKey

[Peter Krempa]

Using of a incorrect value for the --holdtime option was silently
ignored and 0 was used. In case a negative number was used, it
overflowed as the API expects a unsigned int.

Fix the data type and getter function type and report errors on
incorrect values.
