+++ This bug was initially created as a clone of Bug #523941 +++ Description of problem: When trying to install 32b Fedora as a PV guest under RHEL-5.4 Xen, the installation kernel hangs at the very beginning and doesn't even print a single line. However, 64b kernel works fine. Version-Release number of selected component (if applicable): Reproduced with 2.6.31-12 and 2.6.31.14 How reproducible: 100% Steps to Reproduce: 1. virt-install --nographics --paravirt --name=f12-32 --ram=1500 --file=/var/lib/xen/images/virval/f12-32.img --file-size=4 --location=/mnt/download/fedora/linux/development/rawhide-20090916/i386/os Actual results: Nothing. Not a single line of message from the kernel. Expected results: Happily booting kernel. Additional info:

I see similar stuff with 2.6.31-27.el6.x86_64 on a RHEL5.4 domO. The PV guest crashes before installation starts and xen logs do not reveal anything useful. This is with RHEL6.0-20090930.0. rawhide-20090930 is able to boot but it has kernel-2.6.31.1-48 xend.log says: [2009-10-01 08:35:47 xend.XendDomainInfo 4999] ERROR (XendDomainInfo:2129) XendDomainInfo.destroy: xc.domain_destroy failed. Traceback (most recent call last): File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 2125, in destroy xc.domain_pause(self.domid) Error: (3, \047No such process\047)
More info: /usr/lib64/xen/bin/xenctx -s System.map-2.6.31-27.el6.x86_64 4 xc_domain_pause: No such process
FYI: this setup dom0/domU works fine with KVM.
I suggest we add this kernel to the boot partition and grub.conf of a working image. And add console=hvc0 earlyprintk=xen to kernel command line. Then try to boot it with virsh create. Hopefully we'll see something.
Ah wait a moment, Alexander you must be see in a different problem. You say you're trying to boot 2.6.31-27.el6.x86_64, but this bug is for 32-bit DomU on 64-bit Dom0. You'll need to open a new bug describing exactly what you're trying to install.
I've tried i386 PV guest but hit bug #526730. After this is fixed I can know if I'm seeing a separate issue or not.
Andrew, this was a bit more confusing so I'm hesitant to close it myself. However, the rebase of the RHEL6 kernel to 2.6.32 should have brought in all the fixes, in particular 33df4db04a79660150e1948e3296eeb451ac121b x86: xen, i386: reserve Xen pagetables d560bc61575efae43595cbcb56d0ba3b9450139c x86, xen: Suppress WP test on Xen Right?
Yeah, this one was ugly. And another commit needed is 33b6563da26335fbe6834b743ddd00fa8f7ab09a The Fedora BZ that this BZ is cloned off was never closed, since it was never clear that a boot problem caused by a patch that set up slab allocators earlier in the boot sequence was truly fixed, or if it was only masked. We've had a lot of run time on F12 now though since it was released months ago. I think we're safe to close that BZ and set this one to modified. All 3 needed commits are already in RHEL6.
Red Hat Enterprise Linux 6.0 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you.
