[libvirt-users] Libvirt-LXC bug/error
by Samuel Hassine, Another Service 17 Jan '12

17 Jan '12

Hi all, I am trying to run LXC containers with the libvirt utils. I encountered many difficulties but solved all of them, except a last one... This is why I need your help. My problem is simple, here is the log of the command: http://pastebin.com/2zrjYLiT When I try to do: virsh --connect lxc:/// start instance-00000010 I have the errors: 2012-01-16 10:46:47.739+0000: 1: error : lxcContainerMountDevFS:518 : Failed to mount /dev/pts in container: No such file or directory And others (see the trace on pastebin). Does anybody have an idea about how to deal with this problem? Thanks for your answers. Best regards. Sam

[libvirt-users] web frontend for managing libvirt servers
by Christian Parpart 17 Jan '12

17 Jan '12

Hi all, I know that redhat has some web based GUI for managing libvirt clusters, however, I am not having purchased redhat :-) Is there any good open-source web frontend you can recommend for managing your libvirt instances? Ideally with VNC/spice support for connecting to the remote? I know of proxmox, which we used so far for our openvz containers, but I am about to migrate to KVM (and possibly linux-vserver / LXC). Many thanks, Christian.

Hallo Christian, have look on ovirt (redhat). ovirt-node.x86_64 : The RHEV Hypervisor daemons/scripts ovirt-node-tools.noarch : RHEV Hypervisor tools for building and running an RHEV Hypervisor image Dunno if you can compare it too vmware vcenter, but ovirt is what i think you need to manage vm's and hosts. clustering motion etc Its in the Repos for Centos.

Yeah, i bet it will work with them :) Ok Ok, Tada!!!! after recompiling with the recommended useflags and "restarting" of libvirt = Tada! It works! Is the logfile informativ for you? Marko Btw, on my Centos6 Boxes all is running like a charme. Well, Centos/RHEL have strict dependencies for packages and therefore force user to install many packages which user doesn't need in the end. That's why we are using Gentoo, right? :) Yes, right. But for customer related server i feel good to use enterprise linux. Gentoo is my personal fav and love ;-) I wanted to give a try on latest vanilla 3.2.1 - it works like charm now , libvirt, virt-manager. Only trick i have to use is, before creating new virtual machine, i have to a new harddisk for the vm. When i do this in the process of creating new virtual machine, i cant select (in step 3?) where to define the disk. the windows just pop up for 1 sec and is gone, i have to kill then the virt-manager and restart all. what i really like is, when use Centos as Guest, u can use virtio from beginning on hard disk and ethernet. E.g. on Centos it is not easy to install just libvirt without qemu. However, it is perfectly simple to do so on Gentoo. Michal

Hello to the list at first - i am first time here. i setup on my gentoo box libvirt and virt-manager. when i fireup virt-manager all seems okay. when i want to create a new virtual machine it seems all okay, until the step when i want to add an iso image to the cdrom. i notcied that i cant choose to connect cdrom, also the network is not found. i can post error codes from log when needed, just wanted to ask, if someone here had same behaviour and a solution for it. marko

[libvirt-users] Clone VM
by Boris Tobotras 16 Jan '12

16 Jan '12

Greets, I've began to try libvirt API and looking for most correct way to clone existing VM (Xen server if it matters). Since API lacks this functionality how does one usually go about it? Thanks in advance, -- Best regards, -- Boris. We have a lot of strategies, but always the same tactics.

Hello! I just installed the qemu package 1.0. Trying to start my vms with libvirt (virt-manager) resulted in the following error message: internal error cannot parse /usr/local/bin/qemu-system-arm version number in 'QEMU emulator version 1.0, Copyright (c) 2003-2008 Fabrice Bellard' After that I installed the qemu package 0.15 and i didn't receive error. But i have problems with device virtio-balloon-pci: internal error process exited while connecting to monitor: qemu-system-arm: -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4: Bus 'pci.0' not found Libvirt doesn't support qemu 1.0 or it only couldn't parse version of emulator? -- Regards, Belyaev Alex

[libvirt-users] Libvirt API for C/C++ : Monitoring Support
by pratik.patel＠snstech.com 12 Jan '12

12 Jan '12

Greetings, I am a developer, trying to develop a system for monitoring Servers and Virtual Machines using Libvirt API for C/C++. I am facing an issue that there are no functions for monitoring some parameters which I have listed below. I would like to know if there is any there way I can retrieve these parameters since they are critical to my Monitoring Application. Also I am using CentOS 5.6 as a development machine which only supports up to libvirt-devel package version 0.8.2 due to which I am unable to use the newer development binaries (which are only built for newer RedHat kernels) which have support for certain functions that do not work on the one I am using. List of parameters: For Server Monitoring: 1. Memory Swap-In 2. Memory swap-Out 3. Disk Usage 4. Disk Read 5. Disk write 6. Disk Total Read Latency 7. Disk total Write Latency 8. Network Usage 9. Network Packets Received 10. Network Packets Sent 11. CPU utilization 12. CPU Usage For Virtual Machine Monitoring: 1. Memory Utilization 2. Memory Consumption 3. Memory swap-In 4. Memory Swap-Out 5. Disk Usage 6. Disk Read 7. Disk Write 8. Disk Total Read Latency 9. Disk total write Latency 10. Network Usage 11. Network Packets Received 12. Network Packets Transmitted 13. CPU utilization 14.

[libvirt-users] LXC with RHEL 6.1
by John Paul Walters 12 Jan '12

12 Jan '12

I'm trying to start a RHEL 6.1 container on an RHEL 6.1 host through libvirt 0.9.3. I've removed most of the startup services from the guest container, except the network and sshd. I can get the system to boot to a login prompt and can access the console through virsh; however, as soon as I authenticate, I get the following error message: Cannot make/remove an entry for the specified session init: tty (/dev/tty1) main process (372) terminated with status 1 init: tty (/dev/tty1) main process ended, respawning After this, I'm again left at the login prompt. I'm also unable to establish an ssh session, which I assume is related to the issue I'm having with the virsh console. Can anyone offer any suggestions as to what's going on here? I'm using the following XML for my domain creation: <domain type='lxc'> <name>RHEL6</name> <memory>512000</memory> <os> <type>exe</type> <init>/sbin/init</init> </os> <vcpu>1</vcpu> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount'> <source dir='/media'/> <target dir='/'/> </filesystem> <interface type='network'> <source network='default'/> </interface> <console type='pty' /> </devices> </domain> Any thoughts? best, JP
