qemu 2.7 / iPXE

Anyone else having trouble with PXE boot after the latest QEMU upgrade?

When I try to boot from iPXE out of virt-manager (on a newly created domain via 2.7 or previously existing domain from 2.6), it simply immediately moves the machine to a paused state.
Downgrading QEMU to 2.6.1 resolves the issue.

This occurs as soon as the iPXE rom is starting to execute.

Any similar experiences or am I the only one?

Thanks

Re: qemu 2.7 / iPXE

Anway I have opened a bug here:

https://bugs.launchpad.net/qemu/+bug/1623276
https://bugs.archlinux.org/task/50778

The pxe rom file does not seem to have changed from each release as the md5 sums are the same, so I'm at a loss.

Re: qemu 2.7 / iPXE

Have you tried booting qemu without libvirt or virt manager?

I am able to boot from TFTP (dnsmasq + iPXE) on qemu 2.7.0-2 bios/pc mode and efi mode using qemu command line, without virt-manager/libvirt.
