10:14 a.m.
Background :
I have an existing win2K system which consists of one boot-floppy image (boot device)
and one hard-disk partition /dev/sdc1). Previously I got this running with virt-manager
and qemu-0.11 with kqemu - after hitting one bug in virtinst concerning name of the
floppy and applying fix from Cole
http://hg.fedorahosted.org/hg/python-virtinst/rev/4d0ea2274ffd
Yesterday:
tried running same win2k but on a different system - the machine has the Intel VT-x
- OS still Fedora 13, using qemu-kvm.
I applied the above patch to this system's virt-inst, and tried basically same
virt-install command other than to select virt-type of kvm instead of kqemu
virt-install --connect qemu:///system --name=OCFwin2k --ram=392 --cpuset=0
--description="win2k on OCFed disk on usb, nat network" --import
--network=network=default,model=pcnet --virt-type=kvm --accelerate --vnc --vncport=5905
--video=cirrus --disk=/home/lumby/Downloads/win2k_boot.floppage,device=floppy
--disk=/dev/sdc,device=disk --os-type=windows --os-variant=win2k
But this time I hit two new problems :
. another (different) one relating to the floppy - qemu-kvm couldn't find it
. wrong syntax for the usb tablet in qemu-kvm command meant no tablet.
The qemu-kvm command that virt-manager came up with was this:
/usr/bin/qemu-kvm -S -M fedora-13 -cpu n270,+x2apic -enable-kvm -m 392 -smp
1,sockets=1,cores=1,threads=1 -name OCFwin2k -uuid 8a63ef02-cea8-cc23-5a31-f98a1b0bdea1
-nodefaults -chardev
socket,id=monitor,path=/var/lib/libvirt/qemu/OCFwin2k.monitor,server,nowait -mon
chardev=monitor,mode=readline -rtc base=localtime -boot a -drive
file=/home/lumby/Downloads/win2k_boot.floppage,if=none,id=drive-fdc0-0-0 -global
isa-fdc.driveA=drive-fdc0-0-0 -drive file=/dev/sdc,if=none,id=drive-ide0-0-0 -device
ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0 -device
pcnet,vlan=0,id=net0,mac=52:54:00:97:f6:b9,bus=pci.0,addr=0x4 -net
tap,fd=45,vlan=0,name=hostnet0 -chardev pty,id=serial0 -device isa-serial,chardev=serial0
-usb -device usb-tablet,id=input0 -vnc 127.0.0.1:5 -k en-us -vga cirrus -device
virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3
I've attached at the bottom the xml that virst-inst built for this machine.
I then looked back at what qemu command the virt-manager on my other system had come up
with, merged bits of that with the above, and came up with this one which worked ok.
It's a whole lot simpler!
/usr/bin/qemu-kvm -M fedora-13 -m 392 -smp 1 -name OCFwin2k -localtime -boot a -drive
file=/home/lumby/Downloads/win2k_boot.floppage,if=floppy,unit=0 -drive
file=/dev/sdc,if=ide,bus=0,unit=0 -net nic,macaddr=52:54:00:d7:84:4e,vlan=0,name=net0 -net
tap,fd=17,vlan=0,name=hostnet0 -serial pty -parallel none -usb -usbdevice tablet -vga
cirrus
I think there must be a bug or two somewhere but whether in virt-manager or in virt-inst
or both I don't know. If you want more information just ask.
