I'm not sure this will be a bisectable issue, although it's worth a shot to see what results we get with earlier kernels. The thing is I only know of crash being used once with Xen guests during RHEL6's development and it was on an HVM guest about a month and half ago (-25 kernel?). This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux major release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Major release. This request is not yet committed for inclusion. Any prior RHEL6 xen guest work was done as an HVM guest. After taking a relatively quick look at this by trying to find out why we can't even run on a live system, it fails when the first non-unity-mapped kernel virtual-to-physical address translation was attempted. As it turns out, the whole MMU infrastructure is using the pv_mmu_ops[] table that is filled with the functions from "arch/x86/xen/mmu.c". So apparently RHEL6 PV guests have never been tested to date, because the crash utility has *never* supported Xen guest kernels that use the upstream pv_ops[] infrastructure. (It only works in paravirutal mode with the RHEL5 "built-in" xen kernel) Anyway, if we can't run live, it's not even worth looking at the dumpfile issue, which looks to be a different matter entirely. So AFAICT, I'm back at square 1, trying to figure out how the upstream/RHEL6 Xen PV MMU infrastructure actually works. If we use the time it took to get RHEL5 xen kernel support working as a guide, doing just that took me several weeks (months?) to get working. Perhaps I'll get lucky, but this could very well be a major, time-consuming project. So for now, there's no chance of kdump/crash working with RHEL6 PV guests. Note that this affects both x86_64 and x86 RHEL6 PV guests, so there's 4 crash support issues to address: x86_64 live x86_64 virsh dump x86 live x86 virsh dump We (Don and I) had no luck installing a RHEL6 32-bit x86 guest. When anaconda was about to start up, the screen went blank forever; we tried it multiple times. In any case, I'll start work with "x86_64 live" system support first. > Dave, > > see if virt-manager gives you a place to add cmdline params to install. > > need to add: spinlock-type=ticket > > when virt-manager gets to repo to pt to, see if there's > a line to add cmdline params. virt-manager does have that option -- so I added it, and saw it on the final confirmation page, but it still hangs...
