Hi, I'm trying remote connection with qemu hypervisor on FSL PPC board. The libvirt server is the PPC board. root@ppc:~# ifconfig eth0 10.193.20.109 root@ppc:~# libvirtd -d root@ppc:~# virsh -c qemu:///system define test.xml root@ppc:~# virsh -c qemu:///system start test root@ppc:~# virsh -c qemu:///system list --all Id Name State ---------------------------------------------------- 2 test running Connect from an X86 PC (Ubuntu 10.04) to the PPC board. user@x86:~$ virsh -c qemu+ssh://root@10.193.20.109/system list --all The authenticity of host '10.193.20.109 (10.193.20.109)' can't be established. RSA key fingerprint is 2f:56:07:08:da:7d:ac:41:45:57:d2:12:15:19:67:e0.

by yue 08 Apr '13

08 Apr '13

hi,all i now test selinux(enforcing). i assign a nfs-image to a VM, then start it. at the beginning i set virt_use_nfs on, its image does not has a MCS corresponding to qemu-kvm process's MCS then i remount nfs with -o context="system_u:object_r:virt_image_t:s0" , restart VM, its image does not has a corresponding MCS. #ls -lZ ####system_u:object_r:virt_image_t:s0 803003d2-3a2b-4581-a7cb-dc7fac06e7af why this happen? if this is right for NFS? thanks

by Stefan Hajnoczi 08 Apr '13

08 Apr '13

Good news! QEMU.org has been accepted to Google Summer of Code 2013. This means students can begin considering our list of QEMU, kvm kernel module, and libvirt project ideas: http://qemu-project.org/Google_Summer_of_Code_2013 Student applications open April 22 at 19:00 UTC. You can already view the application template here: http://www.google-melange.com/gsoc/org/google/gsoc2013/qemu If you are an interested student, please take a look at the project ideas and get in touch with the mentor for that project. They can help clarify the scope of the project and what skills are necessary. You are invited to join the #qemu-gsoc IRC channel on irc.oftc.net where questions about Google Summer of Code with QEMU.org are welcome. Stefan

[libvirt] [PATCH] Generate RFC4122 compliant UUIDs
by Milos Vyletel 08 Apr '13

08 Apr '13

Even though http://libvirt.org/formatdomain.html#elementsMetadata states that it requires RFC4122 compliance UUIDs that are generated by virUUIDGenerate() are not. Neither does virUUIDIsValid() check for RFC4122 compliance. Following patch modifies virUUIDGenerate() to generate valid UUIDs and adds check to virUUIDIsValid() to validate UUIDs.

[libvirt] 1.4.0 memballoon bug?
by Serge Hallyn 08 Apr '13

08 Apr '13

Hi, When I run virsh -c qemu:///system domxml-to-native qemu-argv /tmp/qatest.xml from 1.4.0 with the qatest.xml below (which has no memballoon device specified), I get an 'unspecified error'. Some printf debugging shows that virDomainDefParseXML is automatically adding a virtio memballoon device, but that its memballoon->info.type is 0, not the 1 or 8 which is required at qemuBuildMemballoonDevStr(). This didn't happen at 1.2.0, but I'm not sure where the error was introduced, as I don't see any suspicious changes around any of the relevant functions. So I was hoping to send a patch, but for now I'm just asking for help :) Anyone know what might be going on? thanks, -serge

[libvirt] [PATCH v2 0/2] libvirt_lxc: implement <hostdev caps=net> device isolation in containers
by Bogdan Purcareata 08 Apr '13

08 Apr '13

This set of patches implements <hostdev caps=net> interface isolation in containers, thus allowing an interface NIC to be assigned exclusively to a container-domain. This is done like moving veth devices in container namespaces, only this time it is actual host devices.
