Re: [Xen-devel] Latest unstable detects cpu speed incorrectly



Hi,

Seems like that emulation is not quite working as it should be. domU's are using all the available cpu and then they crash. I did a fallback back to the old behaviour and the virtuals running with tsc_native=1 are working fine.

Hi,

Ok, good to know. Is it always at 1GHz or can it be adjusted? Is there some other new features different from 3.4.1 that I should know?

We are testing the latest xen-unstable and found an interesting bug.
dom0 detects cpu speed correctly but when booting domU it detects it
incorrectly:

"Detected 1000.000 MHz processor."

TSC is emulated at that speed. If you want old behaviour then add
tsc_native=1
to your domain config file.
