[libvirt-users] libvrtd-1.1.0 crashes when attempting to start some (but not all) LXC containers
by Dennis Jenkins 15 Jul '13

15 Jul '13

Hello all, I have two issues: 1) I am unable to start a seemingly correct LXC domain (I cloned it from a working domain). 2) I am able to crash "libvirtd" by attempting to start the cloned domain, but starting the original works just fine. I humbly submit that item #2 is a bug - the "libvirtd" daemon should never crash due to anything the "libvirt" client throws at it. As for item #1, I'm not sure where I went wrong. A full walk-through is below (ending with a DIFF of the XML from the two domains). I created by original domain ("dwj-lnx-dev") a long time ago. Today I created the new domain ("dwj-hfax-dev") as follows: 1) Shutdown "dwj-lnx-dev" 2) Clone the root file system: "cd /vm/lxc/; cp -a dwj-lnx-dev dwj-hfax-dev" (2.5GB, ~5 min) 3) "libvirt -c lxc:/// dumpxml dwj-lnx-dev > a.xml" 4) ${EDITOR} a.xml a) changed MAC address, name, memory, source directory for "/" 5) "libvirt -c lxc:/// define a.xml" 6) Edit "/etc/bind/pri/*" and "/etc/dhcp/dhcpd.conf" on my host. It does not matter is "dwj-lnx-dev" is running or not. Any attempt to start "dwj-hfax-dev" will crash libvirtd. In the past I was asked to turn on some debugging and capture a detailed log ( https://www.redhat.com/archives/libvirt-users/2013-May/msg00076.html) I will do this soon and post my results as a follow up. ostara ~ # uname -a Linux ostara 3.8.13-gentoo #1 SMP PREEMPT Mon Jun 3 17:10:56 CDT 2013 x86_64 Intel(R) Core(TM) i5 CPU 760 @ 2.80GHz GenuineIntel GNU/Linux ostara ~ # equery l libvirt * Searching for libvirt ...

[libvirt-users] OSX: trying to use libvirt 1.1.0 with VirtualBox 4.2
by Brian Candler 15 Jul '13

15 Jul '13

I see that libvirt 1.1.0 should now support virtualbox 4.2, but I'm having problems getting it to work in OSX. I have built it using homebrew, which now has 1.1.0 in its formulae. The error I get when tying to connect is shown below. Any suggestions for where I should look next? The error about "Failed to find user record for uid 'NNNNN'" is odd. libvirtd *is* started automatically, and runs as my own userid (brian, id 502). Each time libvirtd times out, and restarts again, it shows a different uid in this error message. Thanks, Brian.

[libvirt-users] Permission problem with /dev/net/tun
by Thomas Karcher 11 Jul '13

11 Jul '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi lxc folks, the symptom my libvirt LXC container suffers from is: root@depot:/dev/net# ls -la total 0 drwxr-xr-x 2 root root 40 Jun 29 16:26 . drwxr-xr-x 5 root root 480 Jun 29 16:26 .. root@depot:/dev/net# mknod tun c 10 200 mknod: `tun': Operation not permitted The host is an up-to-date AMD64 Ubuntu raring on 3.8.0-25-generic that was formerly installed from precise and then upgraded. The guest is Ubuntu precise; however, I see the same symptom in another raring container on the same host. What I tried to resolve this: 1) On the host, I echoed various stuff to the cgroup device files: cd /sys/fs/cgroup/devices/libvirt/lxc echo "c 10:200 rwm" > devices.allow echo "c 10:200 rwm" > depot/devices.allow echo a > depot/devices.allow ... and I see the successful results in depot/devices.list, but no success. 2) I inserted a line "/dev/net/tun rwk," into /etc/apparmor.d/abstractions/lxc/container-base - no change. (I know, it seems kind of pointless - because it's about permissions to a device, not a path. You may deduce my desperation from this ... SELinux is not active. Mounts on /dev look normal to me: devfs on /dev type tmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) devpts on /dev/ptmx type devpts (rw,nosuid,relatime,gid=5,mode=620,ptmxmode=666) cgroup on /sys/fs/cgroup/devices type cgroup (rw,relatime,devices) Now comes the weird part: Once I umount /dev inside the container, the "hidden" /dev appears which contains a usable /dev/net/tun. So the mknod problem is probably due to the dropped capabilities - but why/how mounts the container a more restricted /dev on top of the prepared one ...?

[libvirt-users] guests not shutting down when host shuts down

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.

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] 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

I need to use an existing windows 7 installation in a virtual machine form a libvirt host running Ubuntu 12.10. Windows 7 installs on two partitions. There a 100MB boot partitiona and then the main partition for the installation. If I boot the laptop (which dual boots), I can select Windows 7 and boot it just fine, or alternative Ubuntu. If I select /dev/sda1 in the virtmanager as the source path I can see dis activity, but in the VM window the "booting from hard disk..." text never does away. If I select /dev/sda2 (where the windows installation resides (and which is not marked as bootable), I get a boot failure right away.

[libvirt-users] best way to provide disk storage for vm without shared storage system
by Vasiliy Tolstov 04 Jul '13

04 Jul '13

Hello. I'm very happy with libvirt and qemu, that great software! (after some playing i want to create golang bindings to libvirt).. Now i provide ext4 fs for qcow2 images (raid1 with two sata disks). Now i don't need live migration (but may need it in feature). What is the best way to provide disks to vm in case of performance, ability to create backups (i don't want lvm snapshots)? As i search from google more speed can take physical storage - lvm. But may be QED or FVD can provide near lvm performance to me? -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru jabber: vase(a)selfip.ru

[libvirt-users] F19 and virt-install
by Jay Vyas 04 Jul '13

04 Jul '13

Hi libvirt: -------- My "short" question is - is there a recipe for installing F19 100% automatically with static IPs? I'm using a combination of url based install with a kickstart script pasted to a gist in order to bootstrap the entire thing. It **used** to work (fedora16), but recently stopped. ------- Note : Right now Im not using the os-variant switch because fedora17+ arent listed as OS variant's in my version of virt-install. That in and of itself could be the problem -- any way to update virt-install's os-variant list? ------ With Fedora 16, I found that the url based install failed due to a corrupt rpm. I assume this is just because f16 isn't supported anymore so errors on the web site for it are not being fixed. With Fedora 18/19/... Im finding other types of errors related to missing downloaded components when the bootstrapping virt-install starts. In particular, a 404 (not found) error when fetching " product.img " from the OS url. Details below. <note, any insights into things I may be missing due to ignorance would also be appreciated here> -------- With Fedora 18: I've noticed that libvirt gives me some errors with the new generation of fedora formatted os's source directories. It looks for a file "product.img", which (I beleive) doesnt exist in fedora17+. In particular, it is looking for the "product.img" file, under http://redhat.download.fedoraproject.org/pub/fedora/linux/releases/19/Fedor… . virt-install --hvm --name f18x86_64a --ram 1024 --file /var/lib/libvirt/images/f18x86_64a.img,size=20 --location http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/fedora/linux/re… 20 -x "ks=<url_to_kickstart_file>" ------- Running "virt-install list", it seems that the only fedoras known to virt-install are up to fedora16: fedora16 : Fedora 16 fedora15 : Fedora 15 fedora14 : Fedora 14 fedora13 : Fedora 13 fedora12 : Fedora 12 fedora11 : Fedora 11 fedora10 : Fedora 10 fedora9 : Fedora 9 fedora8 : Fedora 8 fedora7 : Fedora 7 fedora6 : Fedora Core 6 fedora5 : Fedora Core 5 ------- Do I need to update virt-install in order to install F17+ from source? How is the os-variant used? Im assuming maybe os-variant needs to be updated somehow in order for the virt-install command to behave correctly. -- Jay Vyas http://jayunit100.blogspot.com

[libvirt-users] fsck and guest images
by Jamie Fargen 03 Jul '13

03 Jul '13

Hey! I have some RHEL6 hypervisors and the VMs are in raw qemu image files in a local raid array linux raid + lvm + ext3. When a kernel update is installed a reboot is necessary, usually it has been more than 180 days since the last reboot and the file system is fsck'd and this takes 2-3 hours. I am curious to know if there is any documentation that addresses the pro's and con's of fsck'ing the volume containing /var/lib/libvirt/images. Could fsck make a change to the underlying file system that the guest images are stored on, which the guest operating system may not be able to handle when it runs its own file system maintenance, i.e. fsck or chkdsk. Is file system maintenance on the hypervisor volume storing the VM images redundant to the VM's own file system consistancy utilities. Regards, Jamie Ian Fargen

[libvirt-users] How to set cpuset.cpus dynamically?
by Peeyush Gupta 03 Jul '13

03 Jul '13

Hi all, I have been trying to run a VM on some particular cpu cores. Now the thing is I can set cpuset with virt-install and that will reflect in VM's XML and it will define the affinity. But what about cpuset.cpus? That is inherited directly from the parent. Is there any way to set it when launching the VM? Again, if I have given cpuset during virt-install, why doesn't cpuset.cpus reflect the value instead of inheriting it from parent? Thanks. ~Peeyush Gupta

[libvirt-users] Not able to create two cpusets with exclusive access

Hi all, I am trying to set up exclusive cpu access for two different VMs. Now, in the hierarchy, the directories of both the VM's are inside /libvirt/qemu/$VM. I have 3 cpus on my machine. I have done echo 0 > cpuset.cpus and echo 1 > cpuset.cpu_exclusive for one VM. Now, I am launching another VM using virt-install and I have given the option --cpuset 1. There is no overlapping of cpus here, but still libvirt is showing error that it's unable to create cgroup for the new VM. Is it possible to have two exclusive cpusets inside a same hierarchy? ~Peeyush Gupta
