[libvirt-users] guests not shutting down when host shuts down
by Lentes, Bernd 11 Jul '13

11 Jul '13

Hi, i have a SLES 11 SP2 64bit host with three guests: - Windows XP 32 - Ubuntu 12.04 LTS 64bit - SLES 11 SP2 64bit The SLES guest shuts down with the host shutdown. The others not. When i shutdown these two guests with the virt-manager, they shutdown fine. ACPI is activated in virt-manager for both of them. Acpid is running in the Ubuntu Client. When the host shuts down, the two guests get a signal (excerpt from the log of the host:) =========================================================== 2013-07-07 16:39:51.674: starting up LC_ALL=C PATH=/bin:/sbin:/usr/bin:/usr/sbin HOME=/ QEMU_AUDIO_DRV=none /usr/bin/qemu-kvm -S -M pc-0.15 -enable-kvm -m 1025 -smp 1,sockets=1,cores=1,threads=1 -name greensql_2 -uuid 2cfbac9c-dbb2-c4bf-4aba-2d18dc49d18e -nodefconfig -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/greensql_2.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -drive file=/var/lib/kvm/images/greensql_2/disk0.raw,if=none,id=drive-ide0-0-0,format=raw -device ide-drive,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -drive if=none,media=cdrom,id=drive-ide0-1-0,readonly=on,format=raw -device ide-drive,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0 -netdev tap,fd=17,id=hostnet0,vhost=on,vhostfd=20 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:37:92:a9,bus=pci.0,addr=0x3 -usb -vnc 127.0.0.1:2 -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 Domain id=3 is tainted: high-privileges qemu: terminating on signal 15 from pid 24958 2013-07-08 13:58:29.651: starting up ========================================================== I'm a bit astonished about "no-shutdown" in the commandline, but the sles guest also has it in its commandline, so it should not bother.

[libvirt-users] Connect issue - libvirt.dylib
by Utpal Das 11 Jul '13

11 Jul '13

Hi All, I am trying to use libvirt to connect to hypervisor. I need some help with this. 1. I am using mac os - Mountain Lion. 2. I have installed libvirt using macports. 3. I am able to connect to the vcenter server using virsh tool. 4. However i am not able to connect using libvirt java program. The issue it seems that virt library cannot be found. (Sample output attached). The question is how do i get libvirt.dylib on my mac. Any pointers would be really helpful Re, Utpal Exception in thread "main" java.lang.UnsatisfiedLinkError: Unable to load library 'virt': Native library (darwin/libvirt.dylib) not found in resource path

[libvirt-users] python equiv to perl list_domains()
by Brett Y 10 Jul '13

10 Jul '13

Hey, I'm trying to figure out a way to get a list of the running domains on a dom0. I can get the ID's but I'd prefer the names. We have another script written in perl, but I'm trying to get some other functionality in python as well as work on converting it all to python. It looks like perl has a list_domains() that will, according to the libvirt doc, "Return a list of all running domains currently known to the VMM". And this works for us, but I can't get the same thing in python as listAllDomains doesn't work with the version of libvirt running on RHEL 5.9 >From our machine that will be running the script RHEL 5.9 yum list | grep libvirt libvirt.x86_64 0.8.2-29.el5_9.1 libvirt-python.x86_64 0.8.2-29.el5_9.1 from the dom0 RHEL 5.9 yum list | grep xen xen.x86_64 3.0.3-142.el5_9.2 xen-libs.i386 3.0.3-142.el5_9.2 xen-libs.x86_64 3.0.3-142.el5_9.2 yum list | grep libvirt libvirt.i386 0.8.2-29.el5_9.1 installed libvirt.x86_64 0.8.2-29.el5_9.1 installed This is the error if I try to do listAllDomains from a FC18 box >>> conn.listAllDomains(1) libvir: Remote Driver error : unknown procedure: 273 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3695, in listAllDomains raise libvirtError("virConnectListAllDomains() failed", conn=self) libvirt.libvirtError: unknown procedure: 273

[libvirt-users] Unable to allocate multiple vcpus using virt-install
by Peeyush Gupta 09 Jul '13

09 Jul '13

I am trying to run a VM on Ubuntu 12.04 which in turn is guest on Fedora 18 host. I am using qemu, kvm and libvirt. I tried to run the following command: virt-install --name dsl --ram 1024 --vcpus 2 --cdrom /home/peeyush/Downloads/some_iso_file.iso --disk path=/path_to_disk My machine here runs with only one vcpu. While when I tried the exact same thing on my Fedora 18 host, it shows two cpus. What am I doing wrong? Thanks. ~Peeyush Gupta

[libvirt-users] deadlock on connection loosing

libvirtd will lock if for example kill programm which established connection, only sigkill + restart helps., to reproduce: virConnectPtr libvirt_connection = virConnectOpen("qemu:///system"); if(libvirt_connection == NULL) { std::cout<<"failed to connect to qemu:///system\n"; exit(-1); } exit(0);

[libvirt-users] Custom Live Migration Query
by Aaron Clausen 09 Jul '13

09 Jul '13

I'm using KVM, libvirt and DRBD to come up with a custom mirroring and live migration setup. I have two servers, each running KVM and libvirt, and both using DRBD to mirror guests (which are stored on raw DRBD partitions). If I shut down a guest on one, I can easily get it up and running on the other without issue. I have run into some file system corruption trouble if I try to do a live migration. I have a test script just to test out the bare functionality I'm looking for (this script would run on the second KVM server; kvmserv02): #!/bin/sh if virsh -c qemu+ssh://kvmserv01/system list | grep -q " guest "; then echo "Saving state on remote server..." if ! virsh -c qemu+ssh://kvmserv01/system save guest --running ~/guest.save; then echo "Could not save state of guest" exit 1 fi echo "Setting remote drbd node to secondary..." if ! ssh root@kvmserv01 "drbdadm secondary guest"; then echo "Could not change remote host to secondary for guest's DRBD partition" exit 1 fi sleep 5 echo "Setting local drbd node to primary..." if ! drbdadm primary guest; then echo "Could not change this host to primary for guest's DRBD partition" exit 1 fi sleep 5 echo "Restoring state on local server..." if ! virsh restore ~/guest.save --running; then echo "Could not restore guest state" exit 1 fi echo "Deleting state file on local server..." rm -f ~/guest.save else echo 'guest not running on this host' fi # End of script While the state is restored and the guest comes up on the second server, I end up with filesystem corruptions. My first test guest had its file system pretty heavily damaged after a few moves back and forth. What am I missing here? Or is this just simply a really horrible way to do it? -- Aaron Clausen mightymartianca(a)gmail.com

[libvirt-users] Libvirt and Glusterfs

Hi, I'm trying to use qemu native glusterfs integration with libvirt. It's all working well from the qemu side, but libvirt fails to start a domain with a gluster drive or attach a drive. I have exactly the same error as this person: https://www.redhat.com/archives/libvirt-users/2013-April/msg00204.html [1] I use qemu 1.5.1 with glusterfs 3.4 beta 4 and libvirt 1.0.6.
