[libvirt-users] How to create virtual machine via virsh shell?
by 张光鹏 11 Nov '11

11 Nov '11

Hi, I recently in the study of the knowledge of the libvirt(version 0.9.6) and vmware(esx,esxi,vcenter,vspheere client), I use virshshell doing some work such as create virtual machine(but i get an error like "the connetc driver do not support") , define virtual machine(success but when i start it i get an error like "can not find vmdk file 或其所依赖的快照磁盘之一"). Then I realized to first create a volume , but I again meet a mistake like "internal error Could not create volume: NotImplemented". Excuse me.How should I do the right to create or define a virtual machine and the normal starting it?

[libvirt-users] Can't assign the 2nd MAC address to the VM
by zhouyb13＠sina.com 10 Nov '11

10 Nov '11

to all who read this message, I can't assign the second MAC to the second NIC for a VM. If only use 1 NIC, assigning MAC works. But not for 2 NICs or more. Do anyone has any ideas? I have installed KVM on Ubuntu 11.10 64bit on my laptop. Also created the bridge on the host, and also taps. I created a RHEL 6.1 64bit VM on this environment and run: sudo kvm -m 512 -drive file=/data/vm/kvm/hslt/rhel61_x64_1st,cache=writeback -boot order=c -localtime -net nic,model=virtio,vlan=1,macaddr=52:54:00:12:34:56 -net tap,vlan=1,ifname=tap2,script=no -net nic,model=virtio,vlan=1,macaddr=52:54:00:12:34:55 -net tap,vlan=1,ifname=tap3,script=no It doesn't work and the VM can NOT start. If I change the command to: sudo kvm -m 512 -drive file=/data/vm/kvm/hslt/rhel61_x64_1st,cache=writeback -boot order=c -localtime -net nic,model=virtio,vlan=1,macaddr=52:54:00:12:34:56 -net tap,vlan=1,ifname=tap2,script=no -net nic,model=virtio,vlan=1 -net tap,vlan=1,ifname=tap3,script=no The VM can start, but the second NIC doesn't work in guest VM, and showing like no such device. After change it to: sudo kvm -m 512 -drive file=/data/vm/kvm/hslt/rhel61_x64_1st,cache=writeback -boot order=c -localtime -net nic,model=virtio,vlan=1 -net tap,vlan=1,ifname=tap2,script=no -net nic,model=virtio,vlan=1 -net tap,vlan=1,ifname=tap3,script=no It works well, with 2 NICs in guest VM.

[libvirt-users] Problem with libvirt daemon
by Wouter - Iamotor 09 Nov '11

09 Nov '11

Hello, I have a problem with the libvirt daemon. I have a little php script which should connect with libvirt, but it won't. When I try to start the libvirt daemon I get this error (using the command libvirtd --listen): 2011-11-09 19:35:18.095: 3560: info : libvirt version: 0.9.7 2011-11-09 19:35:18.095: 3560: error : virPidFileAcquirePath:345 : Failed to acquire pid file '/var/run/libvirtd.pid': Resource temporarily unavailable So the daemon won't start and isn't started yet. If I check if the service is running with ps -ef | grep libvirtd I get this output: root 2865 1 0 15:50 ? 00:00:00 /usr/sbin/libvirtd -d root 3149 1 0 19:17 ? 00:00:00 libvirtd -d root 3206 1 0 19:17 ? 00:00:00 libvirtd -dl root 3300 1 0 19:20 ? 00:00:00 libvirtd --listen --daemon root 3356 1 0 19:21 ? 00:00:00 libvirtd --listen --daemon root 3564 3077 0 19:36 pts/0 00:00:00 grep --color=auto libvirtd Here you can see that the service isn't running. How can I fix this problem. There is a .pid file in the /var/run/ directory. I already deleted it and used the command libvirtd -daemon -listen but it won't start. It doesn't show any output but when I use the ps -ef command, I see that the service is not running. Can you please help me? With kind regards, Wouter.

[libvirt-users] libvirt, OSX and VirtualBox - how?
by Brian Candler 09 Nov '11

09 Nov '11

I have a new OSX Lion Macbook and would like to control VirtualBox using "virsh" (as I do with KVM under Ubuntu). I've got this far: * Installed VirtualBox * Installed libvirt (brew install libvirt) But now I'm a bit stuck :-) I ran VirtualBox itself, and created a test VM successfully. If I try to use virsh, this is what I get: Brians-MacBook-Air:~ $ virsh -c vbox:///session error: internal error unable to initialize VirtualBox driver API error: failed to connect to the hypervisor Brians-MacBook-Air:~ $ virsh -c vbox+unix:///session error: Failed to connect socket to '@/Users/brian/.libvirt/libvirt-sock': No such file or directory error: failed to connect to the hypervisor If I try to start libvirtd, this is what I get: Brians-MacBook-Air:~ $ /usr/local/sbin/libvirtd 00:00:18.970: -1: info : libvirt version: 0.9.6 00:00:18.970: -1: error : virNetSocketNewListenUNIX:340 : Failed to bind socket to '@/Users/brian/.libvirt/libvirt-sock': No such file or directory [but directory /Users/brian/.libvirt was created] However, VirtualBox itself is running OK: Brians-MacBook-Air:~ $ VBoxManage list vms "test" {d0d74c25-1dfc-44a4-8a2b-1d25b7972e7c} Furthermore, dtruss suggests that virsh is finding the installed VirtualBox: Brians-MacBook-Air:~ $ sudo dtruss

In the future it is usually best to keep one of the lists on an email; that way, if I'm away or not responding, someone else can help you. I've added libvirt-users to this response. In any case, you have the right idea. Libvirt is a control plane for various different virtualization solutions. Arguably the most popular virtualization solution that libvirt can control is KVM, but it can also manage Xen, VMware ESX, LXC (linux containers), UML, etc. Libvirt provides both tools (like virsh and libvirtd) and APIs for interacting with virtual machines. The APIs are things like virDomainShutdown(), virDomainReboot(), etc. The ruby-libvirt package is a thin wrapper around these APIs, so that you can use this functionality from ruby programs. That is, you would be able to do something like: dom.reboot dom.shutdown from your ruby programs. There are also bindings for other languages such as python, php, and perl. There is a lot more information at http://libvirt.org, and there is more information specifically about the ruby bindings at http://libvirt.org/ruby -- Chris Lalancette

Hi guys, I have a little problem here. When I want to install a virtual machine I get this error: libvirtError: internal error cannot find PCI address for balloon virtio Libvirt is running on a debian 5 system with kvm and of course libvirt.

[libvirt-users] virt-manager: create lxc app container hangs

libvirt-0.9.6-2.fc15.x86_64 virt-manager-0.9.0-7.fc15.noarch I'm trying to use virt-manager create a simple lxc app container just to see how it works. App is /bin/sh, 128 megs, 1 cpu. All seems to go well, but when I click "Finish" and the "Creating Virtual Machine" box comes up, "Creating Domain..." stays at 0B though the slider keeps going back and forth. Nothing in /var/log/libvirt/libvirtd.log No relevant log in /var/log/libvirt/qemu/ Any help appreciated. sean

I've got 2 doubts: 1.I've been trying to write an application using Libvirt's Java API which should run on both Xen and KVM running machines and execute the Xen or KVM code based on the hypervisor used. I want the physical machine to know if it's running Xen or KVM and execute only that code. While using getURI(), I need to use it as conn.getURI() but then I can't use conn without declaring it previously as Connect conn=new Connect("URI"); Is there any way to get the URI used and hence the hypervisor used? 2. This question concerns the usage of the listDomains(). When I run this piece of code in KVM, it works perfectly fine but throws an array out of bounds exception in Xen. Connect conn=null; conn = new Connect("xen:///", true); int[] id = conn.listDomains(); System.out.println("lD of VM " +id[0]); Thanks for your time. P Ramesh
