kvm expect PXE rom to be in /usr/share/qemu

[Bruno Clermont]

Binary package hint: etherboot

in kvm-pxe (tested with version 5.4.4-1ubuntu1)
the rom are located here:

/usr/share/kvm/pxe-e1000.bin
/usr/share/kvm/pxe-ne2k_pci.bin
/usr/share/kvm/pxe-pcnet.bin
/usr/share/kvm/pxe-rtl8139.bin
/usr/share/kvm/pxe-virtio.bin

KVM is looking for those files in /usr/share/qemu:

# cd /
# /usr/bin/kvm -S -M pc-0.12 -cpu qemu32 -enable-kvm -m 256 -smp 1 -name test -uuid 8765045f-966c-64b6-b8ac-eef7890d36fd -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/test.monitor,server,nowait -monitor chardev:monitor -boot nc -drive file=/var/lib/libvirt/images/test.img,if=virtio,index=0,boot=on,format=raw -net nic,macaddr=52:54:00:36:8f:62,vlan=0,model=virtio,name=e1000.0 -net tap,fd=46,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0 -parallel none -usb -vnc 127.0.0.1:0 -vga cirrus
char device redirected to /dev/pts/2
TUNGETIFF ioctl() failed: Bad file descriptor

pci_add_option_rom: failed to find romfile "pxe-virtio.bin"

last line.
if I
# ln -s /usr/share/kvm/pxe-virtio.bin /usr/share/qemu/pxe-virtio.bin
# /usr/bin/kvm -S -M pc-0.12 -cpu qemu32 -enable-kvm -m 256 -smp 1 -name test -uuid 8765045f-966c-64b6-b8ac-eef7890d36fd -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/test.monitor,server,nowait -monitor chardev:monitor -boot nc -drive file=/var/lib/libvirt/images/test.img,if=virtio,index=0,boot=on,format=raw -net nic,macaddr=52:54:00:36:8f:62,vlan=0,model=virtio,name=e1000.0 -net tap,fd=46,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0 -parallel none -usb -vnc 127.0.0.1:0 -vga cirrus

it work.

Same problem :

pci_add_option_rom: failed to find romfile "pxe-rtl8139.bin"

or

pci_add_option_rom: failed to find romfile "pxe-virtio.bin"

Kvm worked with Ubuntu 9.10, but not with 10.04 beta.

Suggestion to make a link doesn't work.

Hi.

the same, temporarily you can download the rom and put in the right directory

This is arguably a kvm bug, in that kvm should check /usr/share/kvm instead of or as well as /usr/share/qemu , so I've added kvm to the affects list.

I can confirm this issue in Lucid as of five minutes ago:

Agreed, this should either be fixed in etherboot or qemu-kvm.

[Dustin Kirkland  (kirkland)]

qemu-kvm already tries to fix this by symlinking /usr/share/kvm -> /usr/share/qemu. However, that doesn't help if kvm-pxe gets installed first.

Personally, I think solving this in kvm-pxe (etherboot) is better. And I'm happy to update my patch to create symlinks instead, if that's preferred.
