kvm and cpu type
Hello Iam using kvm83 on CentOS5.2
my system has 2x dual Core intel CPU
Intel(R) Xeon(R) CPU 5110 @ 1.60GHz
asdetected by Centos.
If I start kvm-qemu with no CPU option everythign works and hte guest machine detects cpu as
QEMU Virtual CPU version 0.9.1
iv I run qemu-kvm -cpu core2duo
the guest hangs at boot time when it detects the CPU.
I do not know how to fix it.
I also do not know if using -cpu swtch can improve performances.
thank you
Rick

Yes, -cpu core*duo is broken in kvm < 84. Please use the default. There's usually no real benefit for anyone to use a specific cpu type, unless you know that you need it.

This is a known problem and has been fixed for the upcoming kvm-84 release.

It shouldn't matter much.
