[libvirt] PCI Passthrough
I'm having a heck of a time trying to figure out how to do PCI
passthrough for a PCI SCSI controller. I need, if at all possible, to
access it so that I can use a SCSI tape drive with a Windows Server
2000 guest. This is xml config I have:
<domain type='kvm'>
<name>testserver</name>
<uuid>f75a2f63-e1bd-72a5-6134-3fcafbcdb970</uuid>
<memory>524288</memory>
<currentMemory>524288</currentMemory>
<vcpu>1</vcpu>
<os>
<type arch='x86_64' machine='pc'>hvm</type>
<boot dev='hd'/>
</os>
<features>
<pae/>
</features>
<clock offset='localtime'/>
<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'>
<source file='/var/lib/libvirt/images/testserver.img'/>
<target dev='hda' bus='ide'/>
</disk>
<disk type='block' device='cdrom'>
<source dev='/dev/cdrom'/>
<target dev='hdc' bus='ide'/>
<readonly/>
</disk>
<interface type='bridge'>
<mac address='54:52:00:50:03:08'/>
<source bridge='br0'/>
<target dev='vnet2'/>
</interface>
<serial type='pty'>
<source path='/dev/pts/7'/>
<target port='0'/>
</serial>
<console type='pty' tty='/dev/pts/7'>
<source path='/dev/pts/7'/>
<target port='0'/>
</console>
<input type='tablet' bus='usb'/>
<input type='mouse' bus='ps2'/>
<graphics type='vnc' port='-1' autoport='yes'
keymap='en-us'/>
</devices>
</domain>
