27.13. Guest configuration files
When you create guests with the virt-manager or virt-install tools on Red Hat Enterprise Linux 5, the guests configuration files are created automatically in the /etc/xen directory. The example below is a typical a para-virtualized guest configuration file:
name = "rhel5vm01"
memory = "2048"
disk = ['tap:aio:/xen/images/rhel5vm01.dsk,xvda,w',]
vif = ["type=ieomu, mac=00:16:3e:09:f0:12 bridge=xenbr0',
"type=ieomu, mac=00:16:3e:09:f0:13 ]
vnc = 1
vncunused = 1
uuid = "302bd9ce-4f60-fc67-9e40-7a77d9b4e1ed"
bootloader = "/usr/bin/pygrub"
vcpus=2
on_reboot = "restart"
on_crash = "restart"
Note that the serial="pty" is the default for the configuration file. This configuration file example is for a fully-virtualized guest:
name = "rhel5u5-86_64"
builder = "hvm"
memory = 500
disk = ['file:/xen/images/rhel5u5-x86_64.dsk.hda,w']
vif = [ 'type=ioemu, mac=00:16:3e:09:f0:12, bridge=xenbr0', 'type=ieomu, mac=00:16:3e:09:f0:13, bridge=xenbr1']
uuid = "b10372f9-91d7-ao5f-12ff-372100c99af5'
device_model = "/usr/lib64/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader/"
vnc = 1
vncunused = 1
apic = 1
acpi = 1
pae = 1
vcpus =1
serial ="pty" # enable serial console
on_boot = 'restart'
Xen configuration files
It is advised not to edit these configuration files as error checking is limited. Use "virsh dumpxml" and "virsh create" to edit the virsh configuration files(xml based) which have error checking and safety checks.
