RHEL (CentOS, Oracle Liux) kernel 2.6.32-358 does not start at XCP
Hi, everyone, Two days ago I have filed a bug to Red Hat https://bugzilla.redhat.com/show_bug.cgi?id=918239 The problem is, that new RHEL-6.4's kernel 2.6.32-358 does not start at HVM on Xen Cloud Platform 1.6 (maybe, also affected XenServer 6.1) I have tested kernels -358 from CentOS, Oracle and -356 from Red Hat both i686 and x86_64 at 2 different server hardware The sympthoms: kernel does not boot at all, does not produce any log; previous (all 2.6.32-279 and 2.6.32-220), and Oracle's kernel-uek work perfectly. Andrew Jones from Red Hat advised me to ask, does anybody else have this issue? Best regards, -- Constantin Dunayev, Kharkov, UA _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

There''s no reason for the BZ to be private. It was opened externally, and there''s nothing in the history indicating its visibility was changed.

My findings are presented in full on the BZ ticket, but in summary: RHEL 6.4 appears to be somewhat viridian aware The final message on the console before the VCPU spins is "Switching to clocksource hyperv_clocksource" and is presumably waiting for an interrupt from a clocksource we do not implement. Disabling viridian for the domain appears to work around the issue: For XenServer,XCP use: xe vm-param-set vm=$VM platform:viridian=false For xl/xm, ensure viridian=false in the VM configuration file ~Andrew
