Hi,
I've been having some trouble lately with iPXE booting.
I'm on Arch Linux
vanilla 4.7.4 kernel
qemu 2.7
libvirt 2.2.0
virt-manager 1.4.0
Since the upgrade from qemu 2.6.1 to 2.7 a few days ago. I'm no longer
able to PXE boot using a bridged network connection.
The PXE boot fails using NAT (host only) networking as well, when on a
domain thats started by virt-manager, or through virsh.
My networking setup is a bridge (br1) (shared device) established by
systemd.
Another machine on my LAN acts as a tFTP server and my router (tomato)
directs all machines to it via this dnsmasq directive:
'dhcp-boot=pxelinux.0,nas,192.168.9.103'
I have used this setup for years without issue.
All other networking functionality appears to be fine if I boot into
existing domains, skipping PXE rom.
This occurs on domains created with 2.6.1 or with 2.7
Reverting to qemu 2.6.1 package corrects the issue.
When I choose PXE boot, the machine immediately moves to a paused state
(crashed). I only see this:
Booting from ROM...
iPXE (PCI 00:03.0) starting execution
Followed by an immediate crash of qemu. The log simply states emulation
error with some other information I don't understand memory contents
perhaps.
I can use qemu virtual networking and boot via local files served over
tfp: eg:
qemu-system-x86_64 -boot n -net nic,model=virtio,vlan=0 -net
user,vlan=0,tftp=/tmp/tftp,bootfile=/pxelinux.0
I have also tried reverting to the 2.6.1 pxe-virtio.rom file while
using qemu 2.7. Still I get the crash.
So this appears to be some issue with how either libvirt/qemu is
interacting with my network?
I'm not sure what to look at next?
Anyone else have similar issues?
Thanks,
Greg
