Description of problem: After upgrade to Fedora 17, my qemu testing script will fail to completelly boot. My ipxe script will get IP address from DHCP server, but unable to resolve hostnames. Download using IP address works well. Version-Release number of selected component (if applicable): qemu-1.0-17.fc17.x86_64 How reproducible: always Steps to Reproduce: 1. qemu-kvm -cdrom ipxe.iso Actual results: iPXE 1.0.0+ -- Open Source Network Boot Firmware -- http://ipxe.org Features: VLAN HTTPS iSCSI FTP HTTP DNS SLAM TFTP AoE SRP bzImage ELF MBOOT PXE Menu PXEXT DHCP (net0 52:54:00:12:34:56)...... ok https://boot.salstar.sk/by_mac/52%3A54%3A00%3A12%3A34%3A56...............

Expected results: booted menu Additional info: My ipxe.iso image is here: http://boot.salstar.sk/ipxe/ipxe.iso Does not matter, if I boot from iso or from tftp. Other network modes works well, this just happen for -net user (which is default).
I fixed this on my system. The problem was in DNS server. My primary DNS server was down. Can qemu use other DNS servers, if first is down? May be qemu can send to guest so many dns=10.0.2.3,dns=10.0.2.4,... parameters as DNS servers in resolv.conf and forward them to proper addresses.
This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
F19 has a dnssearch= option, I think that solves this.
It seems, that this bug is not fixed until today. (It took me some hours today, to find out what is going on :-( ) dnssearch= will make the internal dhcp server send a list, of what is normally configured in /etc/resolv.conf as "domain". So that is another subject.
