Package: ipxe-qemu
Version: 1.21.1+git20250501.dad20602+dfsg-1
Severity: important
Dear Maintainer,
iPXE support no longer appears to be available for network booting of
virtual machines.
For example, a functional libvirt domain definition using
http://boot.netboot.xyz under Bookworm with version
1.0.0+git-20190125.36a4c85-5.1 no longer works: no iPXE boot and
therefore no HTTP requests to network boot are made.
See the attached netboot_test.sh file to reproduce my test.
If I manually install the bookworm version (1.0.0+git-20190125.36a4c85-5.1)
on trixie, the same test becomes functional again, and network booting via
HTTP on http://boot.netboot.xyz works as expected.
This appears to be a significant regression.

Hi Miao Wang
Chainloading with the following options in the provided script works.
<dnsmasq:option value='enable-tftp'/>
<dnsmasq:option value='tftp-root=/usr/lib/ipxe'/>
<dnsmasq:option value='dhcp-match=set:ipxe,175'/>
<dnsmasq:option value='dhcp-boot=tag:!ipxe,snponly.efi'/>
Thanks for your explanation, this is no longer an issue for me.
Cheers.
