[libvirt] [PATCH v3 2/2] qemu: Default hwclock source for sPAPR to RTC

[Kothapally Madhu Pavan]

QEMU fails to launch a sPAPR guest with clock sources other that RTC.
Internally qemu only uses RTC timer for hwclock. This patch reports
the right error message instead of qemu erroring out when any other
timer other than RTC is used.
