Hi Trinath,have you updated your qemu.conf file with the following settings ?user = "root"
group = "root"
clear_emulator_capabilities = 0
and into the cg_group_device_acl = [
/dev/null", "/dev/full", "/dev/zero",
"/dev/random", "/dev/urandom",
"/dev/ptmx", "/dev/kvm", "/dev/kqemu",
"/dev/rtc", "/dev/hpet", "/dev/net/tun",
