Re: [libvirt] How to start a defined domain

 Well, after "make clean", I run the compiled start.c, still won't work.

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&gt; 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&gt; 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.
