[libvirt] List of available libvirt drivers installed?
by Shi Jin 26 Oct '10

26 Oct '10

I am wondering if there is a way to show a list of available libvirt hypervisor drvers installed in an existing libvirt installation. I know based on the version of libvirt, I can find out supported drivers from this matrix: http://libvirt.org/hvsupport.html However, the particular installation may not turn on all available drivers for this particular build. Is there a way to find out? Particularly, I want to find out if the default libvirt coming with RHEL-5/6 supports VMware ESX, and the same for Ubuntu-10.4/10.10. Thanks in advance.

[libvirt] --checksum-fill error on Ubuntu 10.04
by Justin Clift 26 Oct '10

26 Oct '10

Hi us, Just noticed an error message when manually starting libvirtd (built from git) on Ubuntu 10.04, while checking something else: iptables v1.4.4: unknown option `--checksum-fill' It shows up in the initial default network setup: 10:40:19.807: error : virRunWithHook:855 : internal error '/sbin/iptables --table mangle --insert POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill' exited with non-zero status 2 and signal 0: iptables v1.4.4: unknown option `--checksum-fill' Try `iptables -h' or 'iptables --help' for more information. Just a FYI, in case someone wants to look into it. Regards and best wishes, Justin Clift

[libvirt] How to start a defined domain
by 黄亮 26 Oct '10

26 Oct '10

I've create a domain called "vm01" using Virt-Manager, the GUI tool. Now I wanna use libvirt api to control the life cycle of vm01. It went on well with shutdown and reboot, but how to start it became a problem. I was intended to get the virDomainPtr by using virDomainLookupByName api, and then start it using virDomainCreate api. But it turns out that virDomainLookupByName api cannot return a virDomainPtr for a defined but not running domain. That's my situation, what do you suggest I do now? Thanks in advance. 2010-10-26 Lancer

[libvirt] Initial working Mac OS X libvirt client build
by Justin Clift 26 Oct '10

26 Oct '10

Hi all, This is for anyone using the Homebrew package management system on Mac OS X. :) A first working (but still experimental) libvirt formula is online: http://github.com/justinclift/libvirt It includes the libvirt text mode client (virsh), and the libvirt development libraries. If you have time to test it and report success/failure/(etc), please do. Be aware, for the moment, it pulls down a tarred up snapshot of libvirt git, with a few trivial patches applied to make compiling work: What works: + Remote connections using TLS (qemu+tls://) <-- encrypted + Remote connections using TCP (qemu+tls://) <-- not encrypted! What doesn't work: + Remote connections using SSH (qemu+ssh://), if the server has PolicyKit enabled. (possible bug, will look into it) In theory, this means connecting to Ubuntu server should work, as that uses groups to control access rather than PolicyKit. Haven't tried it though, so if you do, please let me know how it goes. ;) Testing and feedback is encouraged. The aim here is to have the libvirt client (virsh) plus development libraries work properly on OS X. Please note, I'm new to OS X, github, and Homebrew, so if you notice things that should be done better/differently/etc, please let me know. :) Regards and best wishes, Justin Clift

[libvirt] Empty "Domain Management" docs page?
by Justin Clift 26 Oct '10

26 Oct '10

Hi all, At the moment, the "Domain Management" page in the docs is empty: http://libvirt.org/archdomain.html Guessing it's as some kind of placeholder. Ideally, what should the contents of this page be? Regards and best wishes, Justin Clift
