Hi Guys,
I am new to kvm development (used to work on Xen). I used qemu-kvm-1.2.0 first, and then due to pci memory size (x64 bit support), I switched from 1.2.0 to qemu-kvm-1.5.0 (same for 1.3.0~). After that, my VM slows down significantly including booting and execution. Also, sometimes kernel messages "CPU stuck for x seconds" show in dmesg. I think CPU scheduling has been changed or should be set up properly, but I have no clue for now. Can anyone help me to figure out this? I really need some fast VMs as I used to run with qemu-kvm-1.2.0.
I am currently running ubuntu-12.10_64 in VM, and my configure was
./configure --prefix=/usr --target-list=x86_64-linux-user,x86_64-softmmu
sudo qemu-system-x86_64 -name vm -m 1g -hda /home/jinho/virt/vms/vm1.img -device e1000,netdev=net0,mac=00:0c:29:f0:bc:33 -netdev tap,id=net0 -vnc
