[libvirt-users] Extending an existing LVM pool - vgextend and pool XML
by Daniel H Barboza 05 Feb '14

05 Feb '14

Hi, I am trying to figure it out the best way to add a disk/partition to an existing LVM pool. A google search led me to this link (a thread from this same mailing list, September 2013): https://www.redhat.com/archives/libvirt-users/2013-September/msg00136.html The interesting part is this: " On 21/09/13 02:15, McEvoy, James wrote: I looked around but could not find any info on how to expand a libvirt managed LVM storage pool. I do not see any virsh command to do it but I was successful using the vgexpand command to add some more storage once I destroyed the pools and then restarted it. I'd like to verify that this is the proper way to grow the storage in a libvirt LVM storage pool. It's not the proper way in principle, but since libvirt doesn't supportto extendthe volume groups for a logical pool yet, it's the only way now. Onehint though,you can try to refresh the pool by command "virsh pool-refresh" afterthe volume group of the pool is extended. I.e, don't have to restart the pool." I've tried this method and it works, but checking the pool XML using "virsh pool-edit <vg_name>" shows that the XML didn't change. Is it intended? The versions I'm using: # libvirtd --version libvirtd (libvirt) 1.1.3 # virsh --version 1.1.3 Any thoughts/comments are welcome. Thanks!

hi, i am using libvirt-1.2.0 which is installed from source. Which i am using to launch instance on xen. its working fine when i am launching vm from the root user. But i am entered as another user means its throwing the error. And libvirt is working fine in that user except the creating vm: Please refer the following things: eucalyptus@cooldharma06:/opt/i-47FD0798$ virsh -c xen:/// WARNING: gnome-keyring:: couldn't connect to: /home/dharmalingams/.cache/keyring-r004e7/pkcs11: Permission denied Welcome to virsh, the virtualization interactive terminal.

[libvirt-users] Management of host device for network passthrough
by Richard Gomes 03 Feb '14

03 Feb '14

Hello, I've configured a network passtrough like this: <interface type='direct'> <mac address='52:54:00:ec:e8:d9'/> <source dev='eth1' mode='passthrough'/> <target dev='macvtap0'/> <model type='rtl8139'/> <alias name='net1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </interface> OK. it works :) There's only one small difficulty: I have to make sure the host network interface is down before I start the VM. Then, after the VM starts, I have to bring the host network interface up by hand. If the host interface is up before the VM starts, the VM fails to start. If I do not bring the host network interface up after the VM starts, the VM cannot effectively communicate using that network interface. Does anybody has a "clean" solution for it, I mean: without employing some external "dirty" script or so?

[libvirt-users] Trouble configuring with macvtap passthrough on Debian Wheezy / Jessie
by Richard Gomes 03 Feb '14

03 Feb '14

( Posting again. Correct subject line now! ) Hello, I'm trying to use macvtap on Debian Wheezy. Actually, I've installed a recent version of libvirt and qemu from Jessie, using wheezy-backports. $ virsh version Compiled against library: libvirt 1.2.1 Using library: libvirt 1.2.1 Using API: QEMU 1.2.1 Running hypervisor: QEMU 1.7.0 I'm trying to configure a macvtap interface like this: <interface type='direct'> <mac address='52:54:00:7b:05:cd'/> <source dev='eth1' mode='passthrough'/> <model type='rtl8139'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/> </interface> The interface eth1 is used exclusively by this VM, so as far as I understand, mode 'passthrough' is enough since I'd like to "plug" the VM straight onto a public static IP. On my /etc/networks/interfaces, I have this: # start :: define eth1 iface eth1 inet manual # end :: define eth1 It does not matter whether eth1 is up or down, when I try to start the VM, I get the following error: Error starting domain: Cannot create macvlan devices on this platform: Function not implemented 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/asyncjob.py", line 66, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1114, in startup self._backend.create() File "/usr/lib/python2.7/dist-packages/libvirt.py", line 866, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: Cannot create macvlan devices on this platform: Function not implemented Trying to solve the issue, I found this: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737097 I've tried to rebuild the package from Debian sources, but apparently, macvtap is already defined, as I've reported to another mailing list.

[libvirt-users] intel quad gigabit nic and pci passthrough
by Ivan Kabaivanov 02 Feb '14

02 Feb '14

Hi all I have a very weird case of pci passthrough. I have a machine with 7 network interfaces, all of them intel. Four of them are on one quad giga ethernet device. If I manually unbind the devices and allow qemu to use them, with intel IOMMU working, everything works like a charm. Here's how I do it manually: root@kybrat (x86_64) ~]$ lspci -nn | grep net 00:19.0 Ethernet controller [0200]: Intel Corporation 82579V Gigabit Network Connection [8086:1503] (rev 06) 02:00.0 Ethernet controller [0200]: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) [8086:107d] (rev 06) 05:00.0 Ethernet controller [0200]: Intel Corporation 82571EB Gigabit Ethernet Controller [8086:10a4] (rev 06) 05:00.1 Ethernet controller [0200]: Intel Corporation 82571EB Gigabit Ethernet Controller [8086:10a4] (rev 06) 06:00.0 Ethernet controller [0200]: Intel Corporation 82571EB Gigabit Ethernet Controller [8086:10a4] (rev 06) 06:00.1 Ethernet controller [0200]: Intel Corporation 82571EB Gigabit Ethernet Controller [8086:10a4] (rev 06) 0c:00.0 Ethernet controller [0200]: Intel Corporation 82572EI Gigabit Ethernet Controller (Copper) [8086:107d] (rev 06) echo "8086 10a4" > /sys/bus/pci/drivers/pci-stub/new_id echo "8086 107d" > /sys/bus/pci/drivers/pci-stub/new_id echo "0000:05:00.0" > /sys/bus/pci/devices/0000\:05\:00.0/driver/unbind echo "0000:05:00.0" > /sys/bus/pci/drivers/pci-stub/bind echo "0000:05:00.1" > /sys/bus/pci/devices/0000\:05\:00.1/driver/unbind echo "0000:05:00.1" > /sys/bus/pci/drivers/pci-stub/bind echo "0000:06:00.0" > /sys/bus/pci/devices/0000\:06\:00.0/driver/unbind echo "0000:06:00.0" > /sys/bus/pci/drivers/pci-stub/bind echo "0000:06:00.1" > /sys/bus/pci/devices/0000\:06\:00.1/driver/unbind echo "0000:06:00.1" > /sys/bus/pci/drivers/pci-stub/bind echo "0000:0c:00.0" > /sys/bus/pci/devices/0000\:0c\:00.0/driver/unbind echo "0000:0c:00.0" > /sys/bus/pci/drivers/pci-stub/bind qemu-system-i386 -enable-kvm \ -m 2048 \ -cpu host \ -machine pc-q35-1.6 \ -drive file=/media/virtual/krym.qcow2,if=virtio \ -net none \ -device pci-assign,host=06:00.1,rombar=0 \ -device pci-assign,host=05:00.0,rombar=0 \ -device pci-assign,host=06:00.0,rombar=0 \ -device pci-assign,host=05:00.1,rombar=0 \ -device pci-assign,host=0c:00.0,rombar=0 \ -cdrom /media/virtual/asg-9.107-33.1.iso \ -boot c \ -vnc :0 \ -runas virtual \ -monitor unix:/media/virtual/control/krym/monitor,server,nowait \ -rtc base=localtime,clock=host,driftfix=none This starts qemu and pci passthrough works nicely. Now, if I try to do the same thing through libvirt, virt-install doesn't like the quad ethernet device pci passthrough and I get the error below: virt-install --name=krym --ram=2048 --vcpus=1 --cpu=host --import --os-type=linux --disk path=/media/virtual/krym.qcow2,format=qcow2,bus=virtio --nonetworks --graphics vnc,port=5900 --virt-type=kvm --machine=q35 --accelerate --host-device=pci_0000_06_00_1 --host-device=pci_0000_05_00_0 --host-device=pci_0000_06_00_0 --host-device=pci_0000_05_00_1 --host-device=pci_0000_0c_00_0 Starting install...

If it was, you can restart your domain by running: virsh --connect qemu:///system start krym otherwise, please restart your installation. If I try to use just one NIC (any NIC, as long as it's not the quad NIC), things do work: virt-install --name=krym --ram=2048 --vcpus=1 --cpu=host --import --os-type=linux --disk path=/media/virtual/krym.qcow2,format=qcow2,bus=virtio --nonetworks --graphics vnc,port=5900 --virt-type=kvm --machine=q35 --accelerate --host-device=pci_0000_0c_00_0 Starting install...

You can restart your domain by running: virsh --connect qemu:///system start krym So I guess libvirt has some problem with the intel quad NIC. I will appreciate any help. Thanks, IvanK.

[libvirt-users] Creating a static Virtio-Serial 'Port'
by Matthew Harrold 02 Feb '14

02 Feb '14

Hi all, I'm having some problems getting Virtio-Serial running as I'd like. I have 10x USB <-> Serial adapters plugged into my VM Host / Hypervisor, acting as a console server. These are currently operated by the VM Host itself, but I would like to move them to a guest. I have used ISA-Serial but it's limited to 4 'ports' per guest. I've setup Virtio-Serial for the guest and it works, I can pass info via serial from the Host to Guest. I'd like to use socat to link the physical USB serial TTY's and the guest serial 'ports' in /dev/pts. This is works fine and the guest can communicate with the Serial <-> USB adapter, however the Guest serial 'ports' are in /dev/pts and they are assigned a number dynamically when the VM is started, so I can't automate socat to run at boot. Is it possible to assign static PTY's in the host, to the Guest? Or, if this needs to be scripted, is there a command I can run to find out which PTY it's on without parsing the XML from a dump? Thanks.

[libvirt-users] Libvirt Error Creating VMs for Nimbus Cloud

Hello, I am having an issue with libvirt in my Nimbus cloud setup. When I use the Nimbus VM creation test scripts on a VMM node (using libvirt), the VM is created without a problem. However, when I attempt to create a new VM using Nimbus (which then tries to create the VM on the VMM node), I encounter the following error: --------------------------------------------------------------------------------------------------------------------------------------------- $ ./nimbus-cloud-client-022/bin/cloud-client.sh --run --name testimage --hours 1 Launching workspace.

[libvirt-users] Looks like blockpull does not accept a subset of the entire chain of backing files
by Richard Gomes 01 Feb '14

01 Feb '14

Hello If I'm not terribly mistaken, looks like libvirt 1.2.1 does not provide ability of merging only a subset of the entire chain of backing files. So, if I have a chain like this: root <- a <-b <- c <- d <- active ... and I'd like to obtain a chain like this: root <- c <- d <- active ... looks like it's not supported, since I'm trying the command / //virsh blockpull domain --path /path/to/c --bandwidth 30 --base /path/to/root// (1) / ... but it complains because /--path /path/to/c/ is not recognized, since only /--path /path/to/active/ is acceptable: / //virsh blockpull domain --path /path/to/active --bandwidth 30 --base /path/to/root// (2) / So, command (1) fails but command (2) succeeds. The point is: How could I obtain the results I'm trying to achieve via command (1) ? I'm new to libvirt, but the article below made me think that what I'm trying to do would be possible: http://kashyapc.fedorapeople.org/virt/lc-2012/snapshots-handout.html ( see section on /blockpull/ ) Thoughts? For your information, my environment is: Compiled against library: libvirt 1.2.1 Using library: libvirt 1.2.1 Using API: QEMU 1.2.1 Running hypervisor: QEMU 1.7.0 Running against daemon: 1.2.1 Thanks -- Richard Gomes http://rgomes.info http://www.linkedin.com/in/rgomes mobile: +44(77)9955-6813 inum <http://www.inum.net/>: +883(5100)0800-9804 sip:rgomes@ippi.fr

[libvirt-users] Dynamically setting permanent memory libvirt-lxc
by mallu mallu 01 Feb '14

01 Feb '14

I'm trying to permanently change memory allocation for a libvirt-lxc domain. So far I tried changing memory in memory.limit_in_bytes under /cgroup/memory/libvirt/lxc/<container>/. This didn't help. It appears that libvirt is not reading changes in cgroup. My requirements are 1) Be able to dynamically change memory of a LXC domain without reboot 2) The memory change must survive LXC domain reboot. Any help would be greatly appreciated

[libvirt-users] libvirt-sandbox question.
by Christopher Stone 30 Jan '14

30 Jan '14

I hope this question isn't considered too off topic for this list, I am trying to reach the libvirt-sandbox developers, but I could not find a libvirt-sandbox specific mailing list, and it seemed to me that libvirt-sandbox was a part of libvirt itself. I am trying to port libvirt-sandbox to run on a CentOS 6.5 system. This wasn't too hard but, I had to do the following: I have used the CentOS repo addon ElRepo to upgrade the kernel to 3.10.28. CentOS normally runs a 2.6.32 kernel. I upgraded glib2 from 2.36 to 2.38.2. I did this by building 2.38.2 from source and installing it into /usr/local. Thus, the 2.36 version still exists in /lib64 and the normal CentOS applications use this version. I built libvirt 1.2.1 from source and installed it into /usr/local. I used: ./configure --with-lxc --with-selinux --with-secdriver-selinux --prefix=/usr/local I built libvirt-glib 0.1.7 from source and installed it into /usr/local. I used: PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --prefix=/usr/local I build libvirt-sandbox 0.5.1 from source and installed it into /usr/local. I used: PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure As a test, I am able to run the libvirt lxc helloworld example: [root@scwnet1 lxc_helloworld]# virsh -c lxc:/// define helloworld.xml Domain helloworld defined from helloworld.xml [root@scwnet1 lxc_helloworld]# virsh -c lxc:/// start helloworld Domain helloworld started [root@scwnet1 lxc_helloworld]# virsh -c lxc:/// list Id Name State ---------------------------------------------------- 9819 helloworld running [root@scwnet1 lxc_helloworld]# virsh -c lxc:/// console helloworld Connected to domain helloworld Escape character is ^] sh-4.1# exit exit Next, I try to use libvirt-sandbox, and I get the following error: [root@scwnet1 tests]# /usr/local/bin/virt-sandbox -c lxc:/// /bin/sh Unable to start sandbox: Failed to create domain: unsupported configuration: Unable to find security driver for label selinux My libvirt config.log shows the SELinux security driver as yes: configure:71172: Configuration summary
