I am currently facing problem with QEMU.
./x86_64-softmmu/qemu-system-x86_64 -k en-us --show-cursor --enable-kvm -smp 2 -m 1024 -hda /var/opt/kvm/img/win7.img -drive if=none,id=drive0,cache=none,format=raw,aio=native,file=cvbd://127.0.0.1:6380/win7.img?block_size=4096 -cdrom ~/virtio-win.iso -vnc :0
This make my VNC client & the VM very slow. This is a remote Ubuntu-14.04 machine.
I have also tried this with no difference in behaviour,
./x86_64-softmmu/qemu-system-x86_64 -k en-us --show-cursor --enable-kvm -cpu host -m 1024 -drive if=none,id=drive0,cache=none,format=raw,aio=native,file=/var/opt/kvm/img/ubuntu14.04.img -device virtio-blk,drive=drive0 -cdrom ~/ubuntu-14.04.3-desktop-amd64.iso -boot d -vnc :0
Please help.
Thanks,
Darshan
