I made no changes to the kernel side so essentially you are running v3.8
unmodified.
guest kernel?
3.8.1
qemu-kvm command line? (leave out the disk and network arguments -- just
the rest)
Actually using virt-manager for this but here's the most relevant part of the
qemu-kvm command line:
/usr/bin/qemu-kvm -name debian_test -S -M pc-1.2 -enable-kvm -m 1024 -smp
1,sockets=1,cores=1,threads=1
ok, I take that to mean qemu-kvm 1.2.
Actually qemu-kvm is launched first, then perf kvm is launched right after,
before the bootloader of the VM using this command line:
perf kvm stat -p <vm-pid> -e kvmmmu:*
I have not been able to reproduce it. Host kernel is v3.8, guest kernel
is 3.8.1-201.fc18.x86_64 (Fedora 18, latest kernel). Host CPU: Intel(R)
Xeon(R) CPU E5540 @ 2.53GHz.
qemu-kvm version is 1.2. Relevant command line (launched manually)
/usr/local/qemu-kvm/1.2/bin/qemu-system-x86_64 -m 4096 -smp
1,sockets=1,cores=1,threads=1 -S -M pc-1.2
That starts the VM with paused vcpus. Then launch perf-kvm-stat:
perf kvm stat -p $(vm-status -b f18) -e kvmmmu:*
VM boots just fine.
When I get some time I can try qemu versions 1.3 and 1.4 to see if it
makes a difference. Any output from the VM or host dmesg? What if you
start qemu manually?
