similar to: Send magic-sysrq from virtual serial console?

I have a KVM guest running on CentOS 5.5 that is in a bad state. I would like to dump the kernel information using magic-sysrq commands, but I cannot figure out how to send a break on the virtaul serial port provided by "virsh console". The guest is a standard install that will respond if I can send a break on the virtual serial port. Is it possible to send a break on the virtual

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

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

Hello, Without using XM, is it safe to write the letter corresponding to the desired sysrq to xenstore in /local/domain/domid/control/sysrq ? Does anything else have to happen? I am working on some backup utilities that utilize the lvm2 library (liblvm2cmd) , libxenctrl and libxenstore. The program will issue a sysrq S to a guest, pause it, take a snapshot then unpause it (all very quickly). An

Hi, I tried to test a wrong operation on purpose again. When I tried xm sysrq command to a inactive managed domain, I saw the following error message.

I apologize if this is a newbie question, but I have been unable to work out how to do this. I am adding code to my installation on dom0 (running CentOS 5.3) to monitor for hardware faults. If there is an issue, I want to propagate the status to all of the domUs (running CentOS 4.x or CentOS 5) running on the host. What are my options to do this?? Thanks! David -------------- next part

Has anyone accessed Xen or the dom0 Linux serial console on the virtual serial port of a Bladecenter blade via Serial-over-LAN?

Two things: 1. I''m not convinced ''xm crash'' is needed - ''xm destroy'' will do this (and if you want a dump, do ''xm dump'' followed by ''xm destroy'') 2. I don''t see the point of the --noreboot option on ''xm dump'' -- I think this command should simply live-dump the specified domain - as

I am running CentOS 5.3 x86_64 as my dom0 and CentOS 5.3 on my domU's. On the dom0, I have two interfaces that are bonded and have tagged VLANs. I can get the networks to the domU's by creating a bridge for each of the VLANS (bond0.3, bond0.4, etc). On the domU, the interfaces show up as eth0, eth1, etc. Is there a way to set up the network on the dom0 so my domU's see a single

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).

Greetings. This is a problem that just started 2 days ago. Neither Wine, nor any config has changed. I even played back an old system backup from when it worked to no avail. Basically, the problem is this: When 2D apps run in Virtual Desktop Mode, they run fine.
