[libvirt-users] Release of libvirt-0.9.2
by Daniel Veillard 06 Jun '11

06 Jun '11

As planned the new release is available at: ftp://libvirt.org/libvirt/ It is a rather large release with near 400 commits included. From an user point of view the main improvement is likely to be when using migration as various work has been done to extend the protocol and to avoid having the migration command stop other concurrent operations (like virsh list).

[libvirt-users] libvirtError: internal error Domain mytest didn't show up

Hi All, I am new using libvirt. I kept on getting the following error when I try to start my VM. Can anyone give me any suggestion on what could went wrong? Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 498, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup self.vm.create() File "/usr/lib64/python2.4/site-packages/libvirt.py", line 287, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error Domain mytest didn't show up Thanks, David

[libvirt-users] io=native
by Troels Arvin 02 Jun '11

02 Jun '11

Hello, Regarding KVM - in particular RHEL 6.1 x86_64: I just did a set of benchmarks comparing the effect of <driver name='qemu' type='raw' cache='none' io='native'/> versus <driver name='qemu' type='raw' cache='none'/> Using Oracle's "orion" tool with an XIV backend, I got: With io='native': Maximum Large MBPS=964.41 Maximum Small IOPS=11797 Minimum Small Latency=7.57 WithOUT io='native': Maximum Large MBPS=727.42 Maximum Small IOPS=7793 Minimum Small Latency=7.56 In other words, setting the io-attribute to 'native' yields a significant performance improvement. I wonder why KVM doesn't simply default to using io='native'. If that can't happen, then I wonder why libvirt doesn't set io='native' for storage attached to a guest after creation. (virt-manager sets io='native' for the first storage, attached during guest setup, but seems to forget for subsequent block-device additions). -- Regards, Troels Arvin <troels(a)arvin.dk> http://troels.arvin.dk/

[libvirt-users] no virtio in virt-manager
by Konstantin Svist 30 May '11

30 May '11

Hi, For some reason, I don't have virtio as an option in virt-manager on one of my computers. I'm using Fedora 14 with virt-preview repo, x64 architecture. It must be some package that I missed, does anyone know what it might be? Thanks

Hi all, I created a two node cluster that manages virtual machines with two servers connected via a cross cable on the network 10.0.0.0/24. I want that machines that runs on different servers in the network 172.16.0.0/24 can see all the others. To make this possible I've configured a vlan on each server: ... ... 5: eth1.111@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 5c:d9:98:b1:4c:4d brd ff:ff:ff:ff:ff:ff inet 172.16.0.0/24 brd 172.16.0.255 scope global eth1.111 inet6 fe80::5ed9:98ff:feb1:4c4d/64 scope link valid_lft forever preferred_lft forever ... ... And created a "lan" network, via virsh: <network> <name>lan</name> <uuid>8ac034c8-553d-b995-5a80-c1c711cb088c</uuid> <forward dev='eth1.111' mode='route'/> <bridge name='virbr1' stp='on' delay='0' /> <ip address='172.16.0.2' netmask='255.255.255.0'> </ip> </network> but with this setup "lan" never comes up because, for some reason, the network is locked: # virsh net-start lan error: Failed to start network lan error: internal error Network 172.16.0.1/255.255.255.0 is already in use by interface eth1.111 What is not clear to me is why, if I turn down the eth1.111 device, start the lan network, turn eth1.111 up and then force the brctl addif command, everything works: # ifdown eth1.111 Removed VLAN -:eth1.111:- # virsh net-start lan Network lan started # ifup eth1.111 Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config Added VLAN with VID == 111 to IF -:eth1:- # brctl addif virbr1 eth1.111 # brctl show bridge name bridge id STP enabled interfaces br0 8000.6c626dd7518e no eth0 virbr0 8000.000000000000 yes virbr1 8000.5cd998b14c4d yes eth1.111 Why manually is possible to make things work? What am I ignoring? Thanks a lot, -- RaSca Mia Mamma Usa Linux: Niente è impossibile da capire, se lo spieghi bene! rasca(a)miamammausalinux.org http://www.miamammausalinux.org

[libvirt-users] libvirt boots from Knoppix-CD but not Debian-CD
by Christian Brandt 29 May '11

29 May '11

Debian Squeeze, libvirt 0.8.3, qemu-kvm 0.15.5 After configuring the cd image the bios screen shows: (tested with virsh, virt-install and virt-manager) Starting SeaBIOS (version 0.5.1-20110523_174945-brahms) Booting from CD-Rom 65MB medium found (bzw. whatever size) Boot failed: Could not read from CDROM (code 000c) ... the cd images (debian6-cd1, debian6-netinst, debian6-buisnesscard) have the correct md5sum an can be mounted, they simply do not boot. On the other hand, a recent knoppix ISO works well. Tested countless times. All access rights are 777. Only special feature: the host is a minimal installation done with debootstrap and contains not much else than libvirt, virt-manager and lxterminal. I am out of wit. Any ideas? -- Christian Brandt life is short and in most cases it ends with death but my tombstone will carry the hiscore

[libvirt-users] kvm.h not found

Hello all, Am attempting to compile the latest version of libvirt against a custom kernel 2.6.32.40 under CentOS 5.6 and see this in the configure output: checking linux/kvm.h usability... no checking linux/kvm.h presence... no checking for linux/kvm.h... no I have tried to change where it is looking using: CPPFLAGS="-I /home/compuser/linux-2.6.32.40/include" ./configure but end up with the same result. What am I doing wrong ? -- Thanks, Phil
