I've run into a nasty bug while trying to install a Linux guest using
VMware Server inside a kvm guest (full dmesg attached and recreate
instructions below bug).

Here is the setup:
IBM LS21 - 2 socket AMD Host, 64-bit mode, kvm-43 on 2.6.22, 4G ram
1. Apply set_cr3 gp fault patch to kvm, rebuild and insert modules.
2. Install Ubuntu Fiesty i386 into a KVM guest
1. qemu-img create -f qcow2 vmware-server.img 50G
2. qemu-system-x86_64 -hda vmware-server.img -m 512 -no-rtc -net tap -net
nic,model=rtl8139 -vnc :1 -cdrom /home/rharper/ubuntu-7.04-desktop-i386.iso
-boot d
2. Download FC-6 i386 disc 1 from some fedora mirror
http://mirrors.kernel.org/fedora/core/6/i386/iso/FC-6-i386-disc1.iso
3. Boot Feisty guest and install VMware Server following this guide:
http://www.ubuntugeek.com/how-to-install-vmware-server-from-canonical-commercial-repository-in-ubuntu-feisty.html
./qemu-system-x86_64 -hda vmware-server.img -m 512 -no-rtc -net tap
-net nic,model=rtl8139 -vnc :1 -cdrom FC-6-i386-disc1.iso -boot c
4. Reboot and Run Vmware-server tool (Applications->System Tools->VMWare
Server Console)
5. Create New Virtual Machine:
1. Typical
2. Linux
3. Red Hat Linux
4. Default location is ok
5. Use NAT
6. 8G is fine, don't allocate and don't split into 2G
7. Finish
6. Stop guest and rerun qemu but with -snapshot (so I don't corrupt the
guest disk)
./qemu-system-x86_64 -hda vmware-server.img -snapshot -m 512 -no-rtc \
-net tap -net nic,model=rtl8139 -vnc :1 -cdrom FC-6-i386-disc1.iso
6. Power on VM
1. Hit enter at Fedora Boot menu
2. Skip disk check
3. Wait for anaconda to start to load - gets to a black screen
At this point, sometimes the bug will trip, other times, I need to do
some work in the host (tar tzvf kvm-43.tar.gz) a couple times and it
trips.
