I'm looking at the <clock> libvirt parameters.
Is there a way to set the guests clock to a specific time/date at virt
startup? I'm trying to virtualize a system with pci passthrough for a
hardware device that wants to always live in pre-2011. The license manager
for the software/hardware has 31-bit overflow of time calculations.
The current process on the physical machine is to power it on, use the bios
to set the hardware date to Jan 1 2010, boot the system, use an RC script
to ntp-set the date now that the hardware is up and running, and then
everything works till next boot. We even have a nice rc script that will
set the clock back to 2010 if you do a clean shutdown/reboot.
I see I can set my clock sync to variable and specify a negative offset -
is there a way to just say "always be jan 10 2010 when you power on"?
