Hi All, I have a ''Soft lock on cpu problem''. The system crushed. First, it become slow... and then not responding then need to press reset..... I have searched it from google and it seems a bug which has alreay been fixed . However, I use yum update kernel-xen xen, and got the latest one. It still got the problem. My system is Fedora 6. Tha latest kernel is 2.6.20-1.2948.*fc6xen. * My Machine is: Quad-core CPU 1.6 Radeon Video Card 4G Memory The system is running fine when started without xen. I suspect that maybe the latest kernel didn''t come with the bug patch?? Do I need to apply the patch myself? Is it hard to do that ?? By the way, for my guest config file, I use vcpu=1, I don''t know if I changed to 4 will help or not? Thanks for your help! I really need help. Please. x. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, Thanks for that! Just wondering, isn''t kernel-xen a product of XenSource? If the redhat kernel-xen is not working, can I just use the XenSource one? Is the XenSource Kernel-Xen not working in fedora, so redhat has to develop it themselves based on XenSource one. or did XenSource ask redhat to develop the kernel-xen for fedora? I just don''t understand. As this bug has been fix in XenSource, right? I was thinking about not using the redhat kernel-xen, use XenSource kernel-Xen may fix the problem?? Can anyone help me clear about this? Sorry for my english.. Now I am gonna to downgrade the kernel to 2.6.19.

Thank Pasi :) >kernel-xen in Fedora is part of the distribution, it''s maintained by Fedora (Redhat) developers. Fedora currently ships kernel-xen-2.6.20, which is a lot newer than the one xensource is shipping (2.6.18). That means fedora developers have ported the xen stuff for the newer kernel.. and there seems to be some bugs in it. And yes, you should be able to use the xensource kernels with the fedora xen hypervisor.. just pick up the PAE kernels, as fedora hypervisor is PAE. -- Pasi> cheers, > x > > Pasi Kärkkäinen wrote: > > >On Mon, May 07, 2007 at 04:08:43PM +1000, Xin Chen wrote: > > > > > >>Hi All, > >> > >>I have a ''Soft lock on cpu problem''.

Thanks Pasi, I downloaded 2.6.18 rpm (because I can''t find 12.6.19 one for downloading) kernel-xen and install it then reboot system with this kernel version. It seems work now! The system is running for one day without crushing. Cheers! I think I wouldn''t install the xensource kernel, it may bring me more troubles. For now I just use 2.6.18, until they fix the bugs. Thanks a lot!! x>kernel-xen in Fedora is part of the distribution, it''s maintained by Fedora >(Redhat) developers. > >Fedora currently ships kernel-xen-2.6.20, which is a lot newer than the one >xensource is shipping (2.6.18).
