But I could use the same way to create VM2. The only differences is the disk images. The vm2.img comes from this command : qemu-img create -f qcow vm2.img 4G The vm3.img comes from the command : qemu-img create -b vm1.img -f qcow vm3.img virsh # create vm3.xml error: Failed to create domain from vm3.xml error: internal error unable to start guest: qemu: could not open disk image /var/lib/libvirt/images/vm3.img virsh # create vm2.xml<b! r>Domain vm2 created from vm2.xml The XML file as below: <domain type='kvm'> <name>vm2</name> <uuid>7cb40798-1247-85e3-5e5b-e044eafbfff3</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686' machine='pc-0.11'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> &n! bsp; <disk type='file' device='disk'> &nb! sp;&nbsp ; <driver name='qemu' type='qcow'/> <source file='/var/lib/libvirt/images/vm2.img'/> <target dev='hda' bus='ide'/> </disk> <disk type='block' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> </disk> <interface type='network'> <mac address='52:54:00:5d:2c:c6'/> <source network='default'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> &nbs! p; <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> <video> <model type='cirrus' vram='9216' heads='1'/> </video> </devices> </domain> <domain type='kvm'> <name>vm3</name> <uuid>7cb40798-1247-85e3-5e5b-e044eafbfff3</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch='i686' machine='pc-0.11'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/! > <pae/> </feature! s> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow'/> <source file='/var/lib/libvirt/images/vm3.img'/> <target dev='hda' bus='ide'/> </disk> <disk type='block' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> </disk> <interface type='network'> &nbs! p; <mac address='52:54:00:5d:2c:c6'/> <source network='default'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> <video> <model type='cirrus' vram='9216' heads='1'/> </video> </devices> </domain> > > I use the command 'qemu-img create -b vm1.img -f qcow vdisk.img' > > create a new image vdisk.img.
