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", ]
