f7 xen won't boot fc6 xen kernel on x86_64
Last modified: 2008-08-02 19:40:35 EDT
I tried running a Fedora Core 6 Xen kernel [1] on a Fedora 7 [2] dom0 on a Core 2 Duo machine (x86_64). The "xm create -c domain.conf" command doesn't seem to do much, for some time the domain shows up in "xm list", but in the end it doesn't boot, and the xm create command keeps hanging without giving output, until finally being killed. [1] fedora/core/6/x86_64/os/images/xen/vmlinuz and initrd.img [2] 2.6.20-2925.11.fc7xen The exact same combination using an i386 Fedora 7 dom0 and an i386 Fedora Core 6 domU works like a charm with no problems at all (on that same machine, configured identically). Strace'ing the xm create process didn't give me much hints that I could understand either. Any steps that I could take to further narrow the problem down? I also tried using the Fedora Core 5 Xen image, and it gave the exact same result.
Is this fullvirt or paravirt? FWIW I can run FC6 paravirt kernels just fine in F7 dom0. However there is currently a problem with SELinux which prevents them from connecting network devices to the bridge, so you should turn SELinux to permissive mode first. (Bug 243219 and bug 245274).
I couldn't reproduce it here, either: With a FC-6 DVD is mounted on /mnt/cdrom: [root@F7-64 ~]# cat /tmp/fc6.conf kernel = '/mnt/cdrom/images/xen/vmlinuz' initrd = '/mnt/cdrom/images/xen/initrd.img' [root@F7-64 ~]# xm create -c /tmp/fc6.conf Using config file "/tmp/fc6.conf". Started domain fc6.conf Bootdata ok (command line is ) Linux version 2.6.18-1.2798.fc6xen (brewbuilder@hs20-bc1-6.build.redhat.com) (gcc version 4.1.1 20061011 (Red Hat 4.1.1-30)) #1 SMP Mon Oct 16 14:59:01 EDT 2006 [...] My dom0 was running kernel-xen 2.6.20-2936.fc7xen. Could you show the contents of the domain.cfg file you are using to reproduce the problem?
