similar to: Cannot console to domU after crashed ssh session

Hi, is there some way to trigger sysrq from the serial console in xenlinux? With native linux it works by sending a break + sysrq letter, in xenlinux it doesn''t work that way though ... cheers, Gerd -- panic("it works"); /* avoid being flooded with debug messages */ _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).

This patch unifys error messag of migrate and sysrq.

Hi, Sorry for the need of the long winded email. Looking for some answers to the following. I am setting up a xen PV domU on top of a LVM partitioned DRBD device. Everything was going just fine until I tried to test the filesystems in the domU. Here is my setup; Dom0 OS: CentOS release 5 (Final) Kernel: 2.6.18-8.1.4.el5.centos.plusxen Xen: xen-3.0.3-25.0.3.el5 DRBD:

kdump operates by booting a fresh kernel to capture the context of a crashed kernel, and so the only way for kdump to dump a kernel is to crash it and cause kdump to invoke its post-crash kernel. You can manually force a running kernel to panic (and invoke a correctly-configured kdump) with the following command sequence: > echo 1 > /proc/sys/kernel/sysrq > echo c >

Hey, I''ve installed Xen 3.0 on a freshly installed Debian Sarge. dom0 is working nicely (kernel 2.6.12.6-xen0). Then I created a domU, again with Debian Sarge, booting Xen''s vmlinuz-2.6.12-xenU. Unfortunately ctrl-c does not work in the domU''s console, neither if I create the domU with "xm create -c ..." nor if I attach to it later. It doesn''t matter

Hi all. I've made a patch for chan_oss.c to enable callgroups and pickupgroups in it (since wasn't enabled). I needed it for a special use of the console (pickup calls arriving to the console from another phone) btw, If someone is interested, I can submit a patch to the bugtracker. I won't do it until that's usefult for someone... since is a very special features that probably no

It'd be very cool if ssh supported something like Apache "virtual hosts". This would make it much more viable to host multiple installs of git on the same server, for example.

I have a physical SLES11SP2/OES11 system that I''ve converted to a domU. It''s boots ok as an HVM, but when I try to boot as a PV it gets stuck. I have the kernel-xen packages installed and confident the menu.lst is correct. If I look at xm console for the VM I get the output below: Any ideas?

Hello all: I have two machines with btrfs, that give me the "blocked for more than 120 seconds" message. After that I cannot write anything to disk, i am unable to unmount the btrfs filesystem and i can only reboot with sysrq-trigger. It always happens when i write many files with rsync over network. When i used 3.2rc6 it happened randomly on both machines after 50-500gb of writes.

What do you mean? Wouldn't the kernel version always be the actual running version of the kernel that was booted?

Hello, I have a small problem with the blktap, that when I use "tap:aio" protocol to access my disk, the domU stop booting with following message: [ 0.185031] PCI: Fatal: No config space access function found [ 0.189998] Unable to read sysrq code in control/sysrq [ 0.350220] i8042: No controller found [ 0.452153]

I am having trouble sending sysrq commands over USB serial, and I'm not sure what else to check. I have two identical machines, each with usb-to-serial adapters, joined by a null modem adapter. One runs an agetty, the other minicom. I can log in over the agetty as a user and it works as expected, until I try to send a sysrq. To send a break in minicom, I type [Ctrl]+[a] then [f]. Then I

I all, I'm using wine 1.1.14 and when I try to play any game all the system crash and become unresponsive: I can't restart X with ctrl+alt+backspace and the Sysrq magic key doesn't work. Wine crashes in about 0 to 10 minutes EVERY time no matter which game I'm playng. I don't know if it is a wine, Xorg, Kernel or nvidia driver problem but a month ago wine worked like a charm.
