[libvirt-users] LXC and syslog seperation (/dev/log)
by James Leu 11 Apr '15

11 Apr '15

Hello, I'm seeing syslog messages "bleed" from the host and other LXC into the messages, maillog, secure logs of other LXCs. I'm using libvirt 1.0.0 on a host with systemd and kernel 3.9.10. Each LXC is running an older non-systemd linux distribution Is this a known issue? Is there a work around? Thank you for you time, Jim -- James R.

[libvirt-users] raw disks used by guest unavailable to host - retrieve them?
by lejeczek 10 Apr '15

10 Apr '15

hi everybody my guests had drives passed though, like here: <disk type='block' device='lun'> <driver name='qemu' type='raw' cache='none'/> <source dev='/dev/sdv'/> <target dev='sda' bus='scsi'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> guests were Windows 8/2012, now after de-defining guests those disks are still unavailable to host's lvm, pvscan doesn't see. Is there a way to fix it? bw. P

[libvirt-users] How to get the real migrate speed (MB/s) in the libvirt.
by Edward Young 10 Apr '15

10 Apr '15

Hi all, I start to migrate a VM with its storage using "virsh migrate --live --copy-storage-all ..." command. I'm wondering whether we can get the migration report when the migration is done. For instance, how long it takes to migrate this VM, the total data transferred and etc.. Thanks! Ed

[libvirt-users] Centos 7.1.1503 + libvirt 1.2.14 = broken direct network mode
by mxs kolo 10 Apr '15

Hi all. I use LXC on Centos 7 x86-64, with libvirt version 1.2.6 and 1.2.12 My container has bridged network: # virsh dumpxml test1 <domain type='lxc'> <name>test1</name> <uuid>518539ab-7491-45ab-bb1d-3d7f11bfb0b1</uuid> <memory unit='KiB'>1048576</memory> <currentMemory unit='KiB'>1048576</currentMemory> <memtune> <hard_limit unit='KiB'>1048576</hard_limit> <soft_limit unit='KiB'>1048576</soft_limit> <swap_hard_limit unit='KiB'>2097152</swap_hard_limit> </memtune> <vcpu placement='static'>2</vcpu> <os> <type arch='x86_64'>exe</type> <init>/sbin/init</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='block' accessmode='passthrough'> <source dev='/dev/data/test1'/> <target dir='/'/> </filesystem> <filesystem type='ram' accessmode='passthrough'> <source usage='524288' units='KiB'/> <target dir='/dev/shm'/> </filesystem> <interface type='direct'> <mac address='02:00:00:1a:a9:54'/> <source dev='br0' mode='bridge'/> </interface> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain> And all was fine, before I accidentally upgraded Centos to 7.1.1503 After upgrade LXC can't start with diagnostic: [root@node14 ~]# virsh start test1 error: Failed to start domain test1 error: internal error: guest failed to start: internal error: Child process (ip link set macvlan0 netns 25263) unexpected exit status 2: RTNETLINK answers: Invalid argument I reinstall libvirt 1.2.14, but catch same error.

[libvirt-users] XML vm configfile with Display using QEMU GTK interface
by Vinícius Ferrão 10 Apr '15

10 Apr '15

Hello guys, I'm trying to start a VM using the QEMU GTK Display Interface instead of a SDL window. But I'm failing. My actual setting is using SDL with this XML line: <graphics type='sdl' display=':0.0' xauth='/home/ploog/.Xauthority'/> I changed to: <graphics type='gtk'> But it fails to start the VM. Any ideias? Thanks in advance,

[libvirt-users] SIGTERM signal to qemu-kvm process
by Jatin Davey 09 Apr '15

09 Apr '15

Hi I am using QEMU 0.12.1 as the hypervisor in my RHEL installation of 6.5. I wanted to know if there are any side-effects with respect to VM image corruption when i use SIGTERM signal to kill a qemu-kvm process which effectively stops my VM running on the host. Appreciate if you can provide me some valuable information in this regard. Thanks Jatin

[libvirt-users] [Libvirt] [virsh] Transport Error during enumeration while connecting libvirt to Hyper-V Server
by Dhaval_Shah1＠dell.com 07 Apr '15

07 Apr '15

Hi all, I am using libvirt 1.1.1. I can successfully able to connect with Qemu driver but when I am trying to connect to the windows Hyper-V using virsh, I am getting failure. [root@localhost hyperv]# virsh version Compiled against library: libvirt 1.1.1 Using library: libvirt 1.1.1 Using API: QEMU 1.1.1 Running hypervisor: QEMU 1.5.3 When I am doing virsh to connect to hype-V I am getting failure that [root@localhost hyperv]# virsh -c hyperv://172.16.67.192 Enter username for 11.16.67.92 [administrator]: administrator Enter administrator's password for 11.16.67.92: error: failed to connect to the hypervisor error: internal error: Transport error during enumeration: Transport initialization failed (2) using gdb I came to know that from the function "hypervEnumAndPull()" it is calling "wsmc_action_enumerate()" and we are verifying the response using "hyperyVerifyResponse" and from there it fails and cleanup is being called. Code : response = wsmc_action_enumerate(priv->client, root, options, filter); if (hyperyVerifyResponse(priv->client, response, "enumeration") < 0) { goto cleanup; } I have correctly done the settings on my hyper-v Server using below commands: winrm set winrm/config/service/auth @{Basic="true"} winrm set winrm/config/service @{AllowUnencrypted="true"} Does anyone knows what could be wrong or I am missing something or can anyone help to solve this issue. Thanks & Regards, Dhaval Shah

[libvirt-users] mlocate/updatedb and btrfs subvolume mounts
by G. Richard Bellamy 04 Apr '15

04 Apr '15

I've just noticed that I'm having issues with finding files using "locate" when those files are on btrfs subvolume mounts. The issue is that updatedb cannot discern the difference between a btrfs bind mount and btrfs subvolume [1]. This generally means that if you're using btrfs subvolume mounts and updatedb at the same time, and you want to index those subvolumes, you'll need to set PRUNE_BIND_MOUNTS to 0 or "no". And then deal with all the cruft that causes. >From the bug above, you can see that the RedHat dev Michal Sekletar is out of ideas. I'm not sure if he's reached out here or not... and if not, he might welcome some help from the folks on this list. Regrads, Richard [1] https://bugzilla.redhat.com/show_bug.cgi?id=906591#c30

[libvirt-users] P2P live migration with non-shared storage: fails to connect to remote libvirt URI qemu+ssh
by Kashyap Chamarthy 04 Apr '15

04 Apr '15

Migration without --p2p works just fine, ie. the below works: $ virsh migrate --verbose --copy-storage-all \ --live cvm1 qemu+ssh://kashyapc@devstack3/system Migration: [100 %] Result: - On the source host, the guest is shut off - On the destination host, the guest is live migratied successfully Migration with "--p2p" fails, a simple test below: First, I should note, I didn't modify any settings in /etc/libvirt/libvirtd.conf on both source and destination hosts, except for libvirt logging filters. (0) On source and destination hosts, SSH keys are setup so that passwordless auth works: $ ssh-keygen -t $ eval `ssh-agent` $ ssh-add .ssh/id_rsa $ ssh-copy-id root@devstack3 (1) Check if the connection to the remote host works w/o a prompt for user credentials (the below works as user and root): $ virsh -c qemu+ssh://kashyapc@devstack3/system Welcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # (2) Perform peer to peer live migration (as root): $ virsh migrate --verbose --p2p --copy-storage-all \ --live cvm1 qemu+ssh://kashyapc@devstack3/system error: operation failed: Failed to connect to remote libvirt URI qemu+ssh://kashyapc@devstack3/system: Cannot recv data: Permission denied, please try again.
