hi,
i run kvm with "-cpu core2duo" option, but /proc/cpuinfo only shows
SSE and SSE2.
my host is Core i7, so i suppose that i should have SSE4 with this
option, but it seems not?
is there any way to get SSE4?
How about just running it with '-cpu host'?
hah, that works, thanks!
but then there are 2 problems:
- "-cpu host" should be exposed in the doc. "kvm -cpu ?" reports no
such option, so i missed it.
- "-cpu core2duo" should enable SSE4, but it doesnt. a bug?
If this model should have contain it, yes.
According to sysconfigs/target/target-x86_64.conf it shouldn't be in
core2duo but does appear in newer ones.
thanks,
Jun
