Hi, I want to create a Domain with two interfaces. I am using LXC hypervisor in the libvirt. My domain XML is shown below: <domain type='lxc' id='1'> <name>srikanth_vm2</name> <memory>500000</memory> <os> <type>exe</type> <init>/bin/sh</init> </os> <vcpu>1</vcpu> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount'> <source dir='/root/lxc/fedora1'/> <target dir='/'/> </filesystem> <interface type='network'> <source network='default'/> </interface> <interface type='network'> <source network='default'/> </interface> <console type='pty' /> </devices> </domain> I am able to define the Domain. But, I am not able to start the Domain. While starting the domain, I am getting the following error: error: Failed to start domain srikanth_vm2 error: internal error Failed to create veth device pair: 512 Can you please let me know where I am going wrong? Regards, Srikanth.
