I receive the following message after trying to run the xp guest: virsh # start xp (xend.err ''Device 0 (vif) could not be connected. Hotplug scripts not working.'') virsh # dumpxml xp <domain type=''xen'' id=''-1''> <name>xp</name> <uuid>0fe4b14b-ce6a-d84c-dc69-1f9e0cce544d</uuid> <os> <type>hvm</type> <loader>/usr/lib/xen/boot/hvmloader</loader> <boot dev=''hd''/> </os> <memory>512000</memory> <vcpu>1</vcpu> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <features> <acpi/> <apic/> <pae/> </features> <clock offset=''utc''/> <devices> <emulator>/usr/lib/xen/bin/qemu-dm</emulator> <interface type=''bridge''> <source bridge=''eth0''/> <target dev=''vif-1.0''/> <mac address=''00:16:3e:72:d3:89''/> </interface> <disk type=''file'' device=''disk''> <driver name=''file''/> <source file=''/var/lib/xen/images/xp.img''/> <target dev=''hda''/> </disk> <disk type=''file'' device=''cdrom''> <driver name=''file''/> <source file=''/var/lib/xen/images/winxp.iso''/> <target dev=''hdc''/> <readonly/> </disk> <input type=''mouse'' bus=''ps2''/> <graphics type=''vnc'' port=''-1''/> </devices> </domain> winxp.iso one provided in such a way: dd if=/dev/cdrom of=/var/lib/xen/images/winxp.iso for an assistance I am very grateful, Goodarz
