[libvirt-users] kvm/libvirt can't use vmdk files? qemu: 'vmdk' invalid format
by Frank Hauptle 15 Nov '11

15 Nov '11

Hi all, I have a RHEL6.1 qemu-kvm hypervisor running a raw image that I need for various reasons to convert to vmdk. I used this process: qemu-img convert server3.img -O vmdk server3.vmdk Then I edited the XML file (/etc/libvirt/qemu/server3.xml) like so: <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='vmdk'/> <source file='/raid5/images/guilder3.vmdk'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' unit='0'/> </disk> Which basically means that I changed raw to vmdk in this line: <driver name='qemu' type='vmdk'/> but when I try to start the VM, I get this: Error starting domain: internal error Process exited while reading console log output: char device redirected to /dev/pts/5 qemu: 'vmdk' invalid format Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 45, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/engine.py", line 959, in asyncfunc vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 1128, in startup self._backend.create() File "/usr/lib64/python2.7/site-packages/libvirt.py", line 330, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error Process exited while reading console log output: char device redirected to /dev/pts/5 qemu: 'vmdk' invalid format This bit is telling: qemu: 'vmdk' invalid format As a test I tried using libvirt to create a vmdk and then add it to an existing VM, and it failed with the same message. Does this mean that libvirt supports vmdk, but qemu-kvm doesn't? IF so, why does libvirt continue to offer it as an option for KVM VM's?? IF this isn't related to libvirt, I apologise, but I'd appreciate any pointers. kindest regards Frank UWA

14 Nov '11

Hello, I have a few vms running on a blade server and i want to log the actual RAM and CPU utilization by these vms. dom.info(), libvirt API call is not giving correct results. It is always showing the max allocated resources. I have tried using virt-top also but same problem persists. Is there any thing that i am missing. -- Jatin Kumar

[libvirt-users] Problem with listDomains() in Xen
by PREETHI RAMESH 12 Nov '11

12 Nov '11

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]); Answer I'd got: Well, your code assumes that id.length is >= 1, but listDomains() can return an empty array when there are no active domains known to libvirt. So you need to check id.length before accessing any element in the array. Follow up- I tried accessing the length of the array and it's 0 all the time. And there are active domains available. In fact, I'm able to getUUID from the domain name. Other functions work fine too. Am I missing something?Can someone please help me? Thanks!

[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.
