install backtrack linux 5 r3 within KVM

KVM host

[root@f18 ~]# libvirtd --version libvirtd (libvirt) 1.0.3 [root@f18 ~]# qemu-kvm --version QEMU emulator version 1.4.0, Copyright (c) 2003-2008 Fabrice Bellard [root@f18 ~]# cat /etc/fedora-release Fedora release 18 (Spherical Cow)

after I completed installing bt5 within KVM , I faced the following error.

error : no suitable mode found

error : unknown command ‘terminal’

vga=791 is deprecated.

To solve this , it seems that we may solve this by switching video model to cirrus.

So I tried to switch video model to cirrus via virt-manager , I faced another error.

XML error: ram attribute only supported for type of qxl

It was caused by the following bug.

Bug 920549 - error shows when changing video from qxl to other models

https://bugzilla.redhat.com/show_bug.cgi?id=920549

To solve this issue , edit the the xml file via “virsh edit” command.

virsh edit <VM name>

edit the following line:

form

<model type='qxl' ram='65536' vram='65536' heads='1'/>

to

<model type='cirrus' vram='65536' heads='1'/>

after switching video mode to cirrus , I am able to boot the BT5R3 within KVM successfully.
