[Bug 1079164] New: DNS does not appear to be working when using QEMU User Networking (SLIRP)
http://bugzilla.suse.com/show_bug.cgi?id=1079164 Bug ID: 1079164 Summary: DNS does not appear to be working when using QEMU User Networking (SLIRP) Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Virtualization:Other Assignee: virt-bugs@suse.de Reporter: tonyj@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I have several guest images. None have functioning DNS anymore using qemu-2.11.0-3.1.x86_64 (I upgraded to latest tumbleweed version) and openSUSE-release-20171213-1.2.x86_64 (qemu in this version was similarly not working). The SLIRP network forwarding through 10.0.2.2 is working, obviously by IP address only. It is the DNS forwarding that is not working. In each host image, /etc/nsswitch.conf is configured "hosts dns". /etc/resolv.conf lists the dns server at 10.0.2.3. 10.0.2.3 responds to guest ICMP. Directly running "nslookup" on the guest results in a timeout. Running tcpdump on the host, filtering for DNS queries shows nothing being forwarded from the guest. guest is being started as 'qemu-system-x86_64 --enable-kvm -m 4096 -smp cpus=2 <image>.qcow'. This has always worked in the past. I'm trying to compare SLE functionality to Fedora/Ubuntu for an existing bug. I'll try and do additional debugging to see what is happening. -- You are receiving this mail because: You are on the CC list for the bug.
