Upgrading to a new version of pxelinux fixes this. We had been running these:
# lenny PXELINUX 3.71 Debian-2008-09-06 Copyright (C) 1994-2008 H. Peter Anvin # Ubuntu lucid PXELINUX 3.63 Debian-2008-07-15 3.86, from Debian squeeze/sid seems to have fixed this. PXELINUX 3.86 debian-20100418 Copyright (C) 1994-2010 H. Peter Anvin et al I looked over the syslinux Debian and upstream changelogs, but nothing jumps out at me. Our other hosts run KVM 85 or qemu-kvm 0.11.1+dfsg-1. They had been fine with pxelinux 3.63 or 3.71 (we PXE boot nearly all our new VMs for OS installation). FWIW, they also seem to be fine with 3.86. -- VNC console doesn't accept keyboard input during PXE boot https://bugs.launchpad.net/bugs/579596 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
