hmm, where are you exactly setting the timezone? Within the guest, the scheduled 
task, or in the libvirt XML description?

The Windows 11 trial VM in question (downloaded from 
https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/ -> 
https://aka.ms/windev_VM_vmware) comes with the timezone within the VM set to 
US/Pacific.

If I also set the RTC clock for the VM in the libvirt XML description after 
conversion like this:
   <clock offset="timezone" timezone="US/Pacific">
     <timer name="rtc" tickpolicy="catchup"/>
     <timer name="pit" tickpolicy="delay"/>
     <timer name="hpet" present="no"/>
     <timer name="hypervclock" present="yes"/>
   </clock>

Then qemu-ga successfully gets installed after a 2 minute delay. If I leave the 
default libvirt XML description at:

<clock offset="utc"/>

then the issue of qemu-ga not installing remains (the task is scheduled to run 7 
hours in the future). So it is clearly an issue of the timezone of the guest and 
what is passed from libvirt to be out of sync.

Would be nice to compare how you test it so we're on the same page. (Also, to 
clarify, I'm running virt-v2v 2.2.0 without the proposed patches)
