This has allowed me to run vm from CLI so that has helped there but not with virt-manager, which now just shows a blank screen. I have a RX480 radeon card which is yearish old so perhaps support for newer cards is not as good. John

[gentoo-user] virt-manager qemu problem
Hi, I am trying to run virt-manager and or qemu with 3d acceleration using virtio-gpu options. When I start the virtual machine in virt-manager all I get is a screen of static (complete screen corruption of lines and blocks) I also get the same problem when trying to start from CLI with the following /usr/bin/qemu-system-x86_64 \ -enable-kvm \ -cpu host \ -smp 8 \ -m 4G \ -net nic,macaddr=52:54:00:12:34:56 -net user \ -soundhw es1370 \ -usb -device usb-tablet \ -show-cursor \ -vga virtio \ -display gtk,gl=on \ -drive file=arch.img,if=virtio & This used to work fine but has recently gone wrong. I have tried several guests all with the same results of corrupted screens. I can start machines with normal qxl options and all is fine so think this is just an issue with virtio 3d acceleration. Any ideas? Thanks John

[gentoo-user] virt-manager and ssh
Does anyone of you use virt-manager to control QEMU/KVM-hosts? I do or try ... and I always get hickups when I edit VM-settings. Tried virt-manager-0.9.5, 0.10.0, 0.10.0-r1 ... same behavior, when I click Save for setting the disks properties it runs into a timeout or something. The connection uses ssh and I access the host via an IPSEC-VPN (running on my router). Normal ssh and/or mosh-sessions are fine. I allow all TCP/UDP-ports through their firewall for my IPs ... but on the target host I see: libvirtd[5742]: No response from client 0x7fa8060eef80 after 5 keepalive messages in 31 seconds which seems to be the issue somehow. Does anyone know this problem? (feels like this server is my test case for nearly all topics right now) Stefan

Have tried a few vms now and seen to be running ok. Was trying to see any differences with VirtualBox (better speed/usability). Can't say there is much in it but only a home user so will not see too much speed difference anyway. Using gui to create images on hard disc and running isos from there. I perhaps should read the documentation but like to try things first before getting too involved. lxc next!!! Thanks for your guidance.

Not sure about brctl as I can't find this? Have started libvirtd and get the following when trying to start virt-manager 20:28:05.083: 5216: info : libvirt version: 0.9.1 20:28:05.083: 5216: error : virCommandWait:1281 : internal error Child process (/sbin/iptables --table mangle --insert POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill) status unexpected: exit status 1 iptables is failing.

So I'd start with that. If you are not going to use virtual networks, then you could simply disable the virt-net USE flag and save yourself some time. As for as iptables. You need the right sub-drivers (or whatever they're called). Basically if you are using virtual networking you need to be able to do NAT.

Re: [gentoo-user] Virt-manager
On Thursday, July 7 at 23:30 (+0100), john said: On Thu, 07 Jul 2011 17:26:18 -0400 Have cleared up error messages using config as suggested. I still get the issue when starting /etc/init.d/libvirtd * Starting libvirtd ... /usr/sbin/libvirtd: error: Unable to initialize network sockets. Check /var/log/messages or run without --daemon for more info. * start-stop-daemon: failed to start `/usr/sbin/libvirtd'[ !! ] * ERROR: libvirtd failed to start You'll have to turn up the logging level of libvirt (to find out exactly what it's trying to do and where it's erroring out). BUT when i start /usr/sbin/libvirtd from command line virt-manager now works. It lets me create vms (yippee) I was unaware that libvirtd was a separate package (thought it was part of virt-manager. After reading your hints it dawned on me that is was seaparate so have enabled more use flags. I should check more carefully the output of emerge -vp. libvirt (not libvirtd) is a seperate package, it (possibly) contains a number of things, including libvirt: the C library that allows you to manage many different types of virtualization platforms using a common API. Python bindings for the above A command-line and shell interface (called virsh) libvirtd, which is a daemon helper used to manage virtualization platforms which don't have their own management service (such as kvm). virt-manager, is a seperate product. It is a GUI interface written in python that is used to talk to manage different types of virtualization platforms. It uses libvirt (its python bindings) to do this. Think of it as a GUI version of virsh. But you don't need virt-manager to use libvirt, and you don't even need libvirtd to use libvirt (e.g. you are interfacing with Xen or VMware hypervisors). That's why I was trying to say it's good for you to figure out what you are trying to do, before you go through the trouble of figuring out how to solve a problem that doesn't even pertain to you and could have been avoided altogether just by choosing the right combination of USE flags. If you are just wanting have a GUI for Xen, for example, you don't even need to worry about libvirtd. If, for example, you are using KVM but you want the VMs to bridge off a physical interface and have no need for virtual networks, then you don't even need the virt-net USE flag. Anyway I am up and running with a big thanks to yourself and will have a closer look at the service another day. Ok
