I found /usr/lib/xen/bin/xenctx on the Xen dom0, but how do I call it? # /usr/lib/xen/bin/xenctx usage: xenctx [options] <domid> <optional vcpu> # /usr/lib/xen/bin/xenctx --help usage: xenctx [options] <DOMAIN> [VCPU] options: -f, --frame-pointers assume the kernel was compiled with frame pointers. -s SYMTAB, --symbol-table=SYMTAB read symbol table from SYMTAB. --stack-trace print a complete stack trace. -k, --kernel-start set user/kernel split. (default 0xc0000000) -a --all display more registers So once it wants "domid" and once DOMAIN. I tried providing the UUID of the VM, but that doesn't work. So how do I find out which parameter I need to give here? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

There isn't a domid, at least I don't see it. I have uuid's, example: # xe vm-list uuid ( RO) : 9ba0d669-911f-c6a3-a40a-ae64bdd5867b name-label ( RW): zarafa13 power-state ( RO): running uuid ( RO) : b7633bd2-1fd0-a73b-ffba-1d7a4a76a40e name-label ( RW): mailsrv13 power-state ( RO): running These are the VMs that are currently hanging. I tried with /usr/lib/xen/bin/xenctx 1 and that gives output, but I have no idea which VM is domid=1. So I need the connex between uuid and domid. How to do that? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Seems we are stuck here, so I just reboot those VMs. It's a pity we couldn't solve it. BTW: The two VMs where openSUSE 11.1 with 2.6.27.48-0.2-xen and openSUSE 11.2 with 2.6.31.12-0.2-xen. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Both systems are openSUSE 11.1, and I installed today's kernel update. Then on reboot it goes: INIT: Switching to runlevel: 6 INIT: Sending processes the TERM signal Boot logging started on /dev/hvc0(/dev/console) at Thu Nov 4 17:49:48 2010 Master Resource Control: previous runlevel: 3, switching to runlevel:6 Shutting down Nagios NRPE done Shutting down httpd2 (not running) done Shutting down memcached done Saving random seed done Shutting down SSH daemon done /etc/init.d/kbd stop done Shutting down Name Service Cache Daemon done and here the VM is stuck. I have to force reboot the VM, it works smooth afterwards. Maybe the upgraded kernel makes the VM hang on shutdown? It seems it doesn't happen on openSUSE 11.2 anymore, but 11.1 is definitely hanging. At least 2 out of 6 VMs had a hang on reboot now. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
