Hello, Is there any documention on "xenconsoled" ? (I have installed xen from source) /usr/sbin/xenconsoled --help Usage: /usr/sbin/xenconsoled [-h] [-V] [-v] [-i] What do the different options mean? Should xenconsoled always be running, even when no "xm console" commands are active? I killed it in error, but now need to know how to start it with it''s default

xenconsoled: do not write the pty under serial in xenstore if xenconsoled is handling a consolepath. The idea is that pv consoles use the "console" prefix in xenstore and emulated serials use the "serial" prefix in xenstore. There is no need to write the pty for a pv console under "serial", considering that xenconsoled is already writing the pty under

One of our machines are being bitten by that bug, once every 2-4 weeks or so xenconsoled dies and all the VMs stop responding intil xenconsoled is restarted. I googled for it and I saw many people reporting it but no solution for it. Does anyone know if it is solved in 5.5? I can't upgrade the box (it's a production box) unless I can prove the problem will go away. thanks in advance

Package: xen-utils-3.2-1 Version: 3.2.1-2 Severity: wishlist Hi, this morning I spend some time to find out how to log console output of Xen guest domains into a file in dom0.

Package: xen-utils-4.0 Version: 4.0.1-2 Hi, When you change XENCONSOLED_ARGS in /etc/default/xend, there's no normal way to apply it. Even if you do '/etc/init.d/xend stop', that doesn't stop xenconsoled, despite the fact the analogous 'start' action did start it. There isn't even a separate init script action to stop it, it has to be killed manually. Same goes for

Package: xen-utils-4.4 Severity: normal Dear Maintainer, the xen-utils-4.4 and xen-utils-4.1 prerm maintainer scripts contain the following code snippet: remove|upgrade) update-alternatives --remove xen-default /usr/lib/xen-4.4 if [ -x "/etc/init.d/xen" ]; then invoke-rc.d xen stop || exit $? fi ;; which, in conjunction with the postinst

Grant references for the xenstore and xenconsole shared pages exist, but currently only xenstore uses these references. Change the xenconsole daemon to prefer using the grant reference over map_foreign_range when mapping the shared console ring. This allows xenconsoled to be run in a domain other than dom0 if set up correctly - for libxl, the xenstore path /tool/xenconsoled/domid specifies the

Hello list! I''ve noticed this problem a couple of times now.. so I''m wondering if it''s a known bug? Symptoms: After "long" dom0 uptime (174 days when it happened now, was something similar on previous times too) cannot start new pv domUs anymore.. pygrub runs and boots the kernel, but kernel newer gets to actually running initrd and the console output

I''m trying to get XCI running on a Lenovo T61 with Intel-based graphics following the steps in the HOWTO in the build directory. I was able to get to the GRUB screen but never get to the "Welcome to XenClient" prompt. When I boot with the full console output, the system hangs indefinitely after "Starting XenConsoled". I''m well trained in the XenServer

Hi everyone, I know this process is started by xend with no command parameters , if I want xenconsoled''s log facility , I must pass the --log parameter . So I change the following line from: os.execvp(''xenconsoled'', [''xenconsoled'']) to os.execvp(''xenconsoled'', [''xenconsoled'',''--log=all'']) but this

Came across this issue in 3.0.2; looks to also be present in the latest unstable sources: # ls -l /var/run/xenconsoled.pid -rwS--x--T 1 root root 5 Aug 31 00:29 /var/run/xenconsoled.pid setuid, group-execute, and sticky...?

Hi, i''m running a two dom0 nodes cluster for HA, and xen domUs running on top, currently it handles 5 domUs. The issue is that there''s a domU that can only run on one node, it''s not possible to start it on the other one. I get a ''b'' status and can''t access the console. Other domUs can start in either node and I can access their console without
