Re: [Libguestfs] [PATCH 1/1] windows: delay installation of qemu-ga MSI

IIUC, you picked 119 seconds, so effectively 2 minutes. IOW, s/1-2/2/
During the first boot, after virt-v2v conversion, Windows installs
the
drivers injected by virit-v2v. When this installation is finished
s/virit/virt/
Windows enforces some kind of internal reboot. This unfortunately
terminates any running firstboot scritps thus killing the installation
s/scritpts/scripts/
of qemu-ga MSI.
IIUC, the expectation is that the Windows installation of the
drivers will be completed *before* this 2 minute delay occurs.
Windows will then reboot, and the delayed GA job will be run
after this reboot ?
The key question is how confident are we that the 2 minute
delay is sufficient ? Is there chance of still hitting the
problem if doing v2v on slow (ie HDD, not SSD) storage
for example ?
