mount -t 9p

http://www.linux-kvm.org/page/9p_virtio Can this setup be added to a guest in /etc/fstab? or verbatim in /etc/rc.d/rc.local I would like a fallback on guest for when the network goes down as it does in branched\rawhide. -- Regards, Frank http//www.frankly3d.com

KVM and UEFI/Secureboot on the wiki
by Cole Robinson 26 Mar '13

26 Mar '13

Hi all, I just added a page to the wiki about testing secureboot with KVM: https://fedoraproject.org/wiki/Testing_secureboot_with_KVM The initial audience is Fedora QA, but the page has all the info needed to get a UEFI guest set up, so if that's interesting to you, give it a look. Questions, comments, edits all appreciated. Thanks, Cole

Connection breaks for my macvtap
by Richa Marwaha 25 Mar '13

25 Mar '13

Hi I am trying to run some KVM fuzz testing where I have a tool called scapy running on my host and guest which changes the data in the IP header of the packages and send it out to the host and vice versa. I have macvtap setup on my host (have tried both VEPA and Bridge mode). My ssh connection to my guest breaks down after having send just 22 packets and also the gnome crashes. I see the following message in the dmesg dbus[545]: [system] Rejected send message, 2 matched rules; type="method_return", sender=":1.0" (uid=0 pid=499 comm="/usr/lib/systemd/systemd-logind ") interface="(unset)" member="(unset)" error name="(unset)" requested_reply="0" destination=":1.17" (uid=42 pid=658 comm="/usr/bin/gnome-session -f --debug ") The connection to the guest restart but wanted to know what makes it breakdown. Regards, Richa Marwaha

05 Mar '13

I have setup on a libvirtd Fedora 18 up to date two centos-6.3 server (web and mail), but it seems that when I shutdown f18, the two hosts are power off without shutdown. How to ensure that the two guests are suspended, hibernate or shut down properly? like Centos 6.3 host do? I have missing some things? Many thanks. -- Dario Lesca - sip:dario@solinos.it (Inviato dal mio Linux Fedora18+Gnome3)
