I used filters like clean-traffic. The filters are working, but I can not see the rules in iptables -L. How can I look through the rules?

[libvirt-users] libvirtd & dnsmasq
by Mark Foster 20 Nov '10

20 Nov '10

libvirtd is starting dnsmasq! This is on RHEL5.5 I don't see it mentioned in /etc/init.d/libvirtd or /etc/libvirt/* or /etc/sysconfig/libvirtd 4337 ? S 0:00 /usr/sbin/dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/default.pid --conf-file= --listen-address 192.168.122.1 --except-interface lo --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-lease-max=253 How can I properly disable this funcationality? (I'm running dnsmasq for other purposes on the host, and the libvirtd incantation conflicts). Thanks. -- Mark D. Foster <mark(a)foster.cc> http://mark.foster.cc/ | http://www.freegeekseattle.org/

[libvirt-users] migration failure
by Mark Foster 19 Nov '10

19 Nov '10

I'm setting up to do live migrations. Running KVM and libvirt on Ubuntu 10.04.1 Guest vhsot23 has qcow2 on NFS share, accessible to both vhost23 and 24 /net/fs11/srv/customer/nfs/kvm/mem52.img root@vhost23:~# virsh migrate mem52 qemu+ssh://vhost24/system At this point, it just sits there. virsh list on both vhost systems show mem52 in a paused state. I check /var/log/libvirt/qemu/mem52.log on the target system vhost24 it states... qemu: warning: error while loading state for instance 0x0 of device 'ram' Further, if I do virsh destroy mem52 on the target it cleans up fine, but after Ctrl-C on the source, mem52 cannot be managed. root@vhost23:~# virsh destroy mem52 error: Failed to destroy domain mem52 error: Timed out during operation: cannot acquire state change lock Only way to recover is manually kill the kvm process id for that guest. Please help me get this to work. -- Mark D. Foster <mark(a)foster.cc> http://mark.foster.cc/ | http://www.freegeekseattle.org/

[libvirt-users] driver type for .vdi images?
by Benjamin Hagemann 18 Nov '10

18 Nov '10

Hello libvirt experts, I use libvirt (0.7.5-5ubuntu27.7) with KVM / qemu (0.12.3+noroms-0ubuntu9.2). Some machines use raw images but same use Virtualbox images (.vdi). Since last Ubuntu 10.04 LTS update I can not start the vdi-images. The "driver name= type=" option was new. <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='vdi'/> <source file='/path/image.vdi'/> <target dev='hda' bus='ide'/> </disk> But when I try "type=vdi" I got in the Log-File: libvir: Security Labeling error : error calling aa_change_profile() so I checked: cat vdi-machine.xml | /usr/lib/libvirt/virt-aa-helper -r --uuid libvirt-XXXXXXXX-XXXXX-XXXX-XXXX-XXXXXXXXXXXX --dryrun -p 0 libvir: Domain Config error : internal error unknown disk format 'vdi' for image.vdi virt-aa-helper: error: invalid VM definition Next I checked libvirt.org: http://libvirt.org/storage.html Valid volume format types raw, bochs, cloop, cow, dmg, iso, qcow, qcow2, vmdk, vpc => But what is the right type for .vdi-Images? By the way, the examples at this site does not know the "driver name= type=" option. Thank you very much. -- Kind regards, Benny gpg 0xFC505AB0 jabber benny(a)benny.de sip benny(a)benny.de

[libvirt-users] Changing default nic and storage types
by Chris Phillips 17 Nov '10

17 Nov '10

Hi, Simple question that I can't track down any notable discussion about, let alone an answer... Is it possible to define what the "default" nic and storage types are? I am deploying images out of cobbler using koan and all of them are running virtio wherever applicable, but this is not the default, and at present there is no way within koan or cobbler to define what type of devices they should be. I've hard coded this device type declaration into koan, but don't like that in the slightest, and would typically expect to be able to just set "default=virtio" in a libvirt config file somewhere. I fear I'm actually not missing anything and it's just hard coded for the most compatible device with no recourse to override it. Thanks Chris

I try to add some rules to filtering network, example <filterref filter='clean-traffic'/> or <filterref filter='no-ip-spoofing'/> and vm not starting with message virsh start freebsd8.2 error: Failed to start domain freebsd8.2 error: internal error IP parameter must be given since libvirt was not compiled with IP address learning support what do I do wrong? libvirtd --version libvirtd (libvirt) 0.8.4

[libvirt-users] (no subject)
by David M. Barlieb 17 Nov '10

17 Nov '10

HI, I've just begun using libvirt as part of my KVM installation and have been having some confusion regarding networking of my virtual guests. I'm not sure if I should even be sending this to this mailing list and if not please let me know and if possible where I should be sending this inquiry. I understand I can setup a dedicated bridged interface for my guest. But as for the virbr interface which is the default, I'm a little confused about. When using this, does the guest os use the same ip as the host? If so, then how to packets get to the guest instead of the host. I would guess there's an alternate mac address for the guest interface and this is how it gets there but am not certain. Sorry if this seems like a simple question but I'm not very well versed in networking. daveb

[libvirt-users] java binding and virtualbox-ose

I'm trying to connect to vbox hypervisor on an Ubuntu 10.04 machine through libvirt java binding (libvirt-java-0.4.6) by simply invoking: Connect conn = new Connect("vbox:///session", false); but I got this exception: libvir: warning : Failed to find the interface: Is the daemon running ? libvir: Remote error : unable to connect to '/var/run/libvirt/libvirt-sock': Connection refused libvir:
