[libvirt] Gtk# help
by arnaud.champion＠devatom.fr 27 Oct '10

27 Oct '10

?Hi, As you maybe have seen in my csharp sample code, I'm not an expert with Gtk# under mono, it's really different from windows form. Can anyone help me with Gtk# to make the bindings samples better ? Arnaud

[libvirt] Libvirt.org "Docs" page (top level)
by Justin Clift 27 Oct '10

27 Oct '10

Hi us, The top level libvir.org Docs page is blank: http://libvirt.org/docs.html Looks like it's only purpose is to show the menu on the left hand side, where people can click documentation headings. The completely empty page content though, kind of looks "wrong", so I'm thinking we should fit it with something. Initial thought is to have an autogenerated list of all the docs pages, expanded out. Pretty much a table of contents kind of thing. But open to suggestions too if someone has better ideas? :) Regards and best wishes, Justin Clift

Re: [libvirt] How to start a defined domain
by 黄亮 27 Oct '10

27 Oct '10

yes, and it works now, both "virsh start vm01" and my program. A lot of thanks to you. But there is still something disturbing. I'm using putty on windows xp connecting to another computer running CentOS which has xen and libvirt on it. After I type "virsh start vm01" or run my program, the terminal freezes, I can't input anything to terminal. And then the network connection to server is closed. Have you been into this? 2010-10-27 黄亮发件人： Osier 发送时间： 2010-10-27 11:25:54 收件人：黄亮抄送：主题： Re: [libvirt] How to start a defined domain ----- "黄亮" <lancerhuang(a)163.com> wrote: > > > nope. > > "vm01" can be seen after I started it using "xm create vm01". > But, if I shut it down using "xm shutdown vm01", it can't be seen > using "virsh list --all" > > I assume that, "vm01" only have a xm config file stored in /etc/xen/, > and libvirt or virsh need a XML style config file.

Do correct me if I'm wrong :-) so it becomes clear now, I guess you didn't 'define' the guest from libvirt side, that means'vm01' is not a persistent domain, so after you shutdown the vm01 using xm, yes, libvirt can't see it anymore. actually even if after you use "virsh destroy" or "virsh shutdown", libvirt can't see it either.. :-) the way to define a domain to be persistent,(assume the domain is running) # virsh dumpxml vm01 > vm01.xml # virsh define vm01.xml then think you can start it via: # virsh start vm01 - Osier > > 2010-10-27 > > 黄亮 > > 发件人： Osier > 发送时间： 2010-10-27 10:56:54 > 收件人：黄亮 > 抄送： > 主题： Re: [libvirt] How to start a defined domain > > > > ----- "黄亮" <lancerhuang(a)163.com> wrote: > > > > > Oh, yeah, you're right, it's "make uninstall" :-) > > > > after uninstall 0.8.4 and reinstall 0.6.3, it still won't work. > > > > but one thing I should mention is that while using "virsh start > vm01", > > it reports the same error, saying can't find domain "vm01" with > > "xenUnifiedDomainLookupByName ". > > So I think maybe there is something I'm missing in define a domain. > > > > Would you give me some hints so I can see where I go wrong?

Re: [libvirt] --checksum-fill error on Ubuntu 10.04
by Osier 27 Oct '10

27 Oct '10

caused by network filter driver depends on the newer iptables, there is no "--checksum-fill" option indeed in older iptables. The following commit log is from iptables git. commit 9d1b11102b53103c00b7fddf4658a4d2bdee1338 Author: Michael S. Tsirkin <mst(a)redhat.com> Date: Thu Jul 15 17:23:24 2010 +0200 extensions: libxt_CHECKSUM extension This adds a `CHECKSUM' target, which can be used in the iptables mangle table. You can use this target to compute and fill in the checksum in a packet that lacks a checksum. This is particularly useful, if you need to work around old applications such as dhcp clients, that do not work well with checksum offloads, but don't want to disable checksum offload in your device. The problem happens in the field with virtualized applications. For reference, see Red Hat bz 605555, as well as http://www.spinics.net/lists/kvm/msg37660.html Typical expected use (helps old dhclient binary running in a VM): iptables -A POSTROUTING -t mangle -p udp --dport bootpc \ -j CHECKSUM --checksum-fill Includes fixes by Jan Engelhardt <jengelh(a)medozas.de> Signed-off-by: Michael S.

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

26 Oct '10

nope. "vm01" can be seen after I started it using "xm create vm01". But, if I shut it down using "xm shutdown vm01", it can't be seen using "virsh list --all" I assume that, "vm01" only have a xm config file stored in /etc/xen/, and libvirt or virsh need a XML style config file. So I can't start vm01 using "virsh start vm01" nor can I see it using "virsh list --all". Is it like this?

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

26 Oct '10

Oh, yeah, you're right, it's "make uninstall" :-) after uninstall 0.8.4 and reinstall 0.6.3, it still won't work. but one thing I should mention is that while using "virsh start vm01", it reports the same error, saying can't find domain "vm01" with "xenUnifiedDomainLookupByName ". So I think maybe there is something I'm missing in define a domain. Would you give me some hints so I can see where I go wrong?

"make clean" won't uninstall the installed stuffs, use "make uninstall" instead, or you just made a typo? :-) after that, suggest re-installing 0.6.3 if you are not sure if it's injured. - Osier > And I forget to metion, an error msg is shown: > > libvir: Xen error : Domain not found: xenUnifiedDomainLookupByName > > is that means I missed something? > > > 2010-10-26 > > 黄亮 > > 发件人： Osier > 发送时间： 2010-10-26 18:05:46 > 收件人：黄亮 > 抄送： > 主题： Re: [libvirt] How to start a defined domain > > > > ----- "黄亮" <lancerhuang(a)163.com> wrote: > > > > > Accroding to your case, it seems I have no need to upgrade libvirt > to > > 0.8.4 > > Will that work if I erase 0.8.4 using "make clean" and draw back to > > 0.6.3 ? > > yep, think so, if you don't need the new features, and 0.6.3 is enough > for your project requirement.. :-) > > - Osier > > > > > > > > 2010-10-26 > > > > 黄亮 > > > > 发件人： Osier > > 发送时间： 2010-10-26 17:10:40 > > 收件人：黄亮 > > 抄送： > > 主题： Re: [libvirt] How to start a defined domain > > > > > > > > ----- "黄亮" <lancerhuang(a)163.com> wrote: > > > > > > > > Thanks for your reply, Osier. > > > > > > > > > The distro I'm using is CentOS release 5.5 (Final) > > > > > > I'm not quite sure about the version of libvirt.
