This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. ** Can you check it w/ pxe/tftp daemon that does not run on the host? (In reply to comment #4) > Can you check it w/ pxe/tftp daemon that does not run on the host?

Can you confirm if you can download the tftp files inside the guest started on rhel6? This is a dupe of bug 594682. It's been identified there as a gpxe issue and passing --dhcp-no-override to dnsmasq helps. Marking as a duplicate. *** This bug has been marked as a duplicate of bug 594682 *** (In reply to comment #6) > This looks like a gpxe issue. > > Can you confirm if you can download the tftp files inside the guest started on > rhel6?

Created attachment 431668 [details] snapshot-could-not-find-tftp-file-root The tftp/pxe installation with public bridge is ok. When I create a private bridge and setup tftp/pxe by dnsmasq, guest can get ip address, but coule not find tftp file/root. Both installation of public bridge and private bridge are ok on RHEL5 host. Version-Release number of selected component (if applicable): dnsmasq-2.48-4.el6.x86_64 kernel-2.6.32-37.el6.x86_64 # rpm -qa |grep qemu qemu-img-0.12.1.2-2.93.el6.x86_64 qemu-kvm-0.12.1.2-2.93.el6.x86_64 qemu-kvm-debuginfo-0.12.1.2-2.93.el6.x86_64 qemu-kvm-tools-0.12.1.2-2.93.el6.x86_64 gpxe-roms-qemu-0.9.7-6.3.el6.noarch How reproducible: always Steps to Reproduce: 1. preapring tftp/pxe files, put kickstart into a floppy image. # find images/tftpboot/ images/tftpboot/ images/tftpboot/pxelinux.cfg images/tftpboot/pxelinux.cfg/default images/tftpboot/pxelinux.0 images/tftpboot/vmlinuz images/tftpboot/initrd.img 2.

Expected results: Guest can find tftp file/root, and complete installation. Additional info: 1.
