Hi All,
Am a newbie (to kvm, linux kernel, git, etc.) so apologize in advance for
missing/inaccurate info.
I am experiencing inconsistent behavior of guest gettimeofday, described below.
I have seen prior reference to the problem, however, it was not clear whether
the issue was solved or not and where.
Below is a description of my setup and the behavior I see.
Another question is whether oprofile with timer mode would suffer from the same
problem?
Probably, yes.
Otherwise I saw that kvm-85 has "generic performance counter msr handling", does
this mean that oprofile can be executed without the timer mode?
No, we don't really emulate the performance counters, only when they're
disabled.
Setup:
Guest 32 bit ubuntu with 2.6.27 kernel
Host 64 bit Suse 10.2 with 2.6.27 kernel
What's the guest clocksource? (/sys/.../current_clocksource)?
1 quadcore Intel Xeon CPU
I am not sure about the kvm userspace code version.
Used git to create a repository, and then did
git checkout kvm-updates-2.6.27 (is that fixed in time?)
That's really old. Just use qemu-kvm.git.
