I have some problems with stability of Debian guests in my XenServer hosts.
To debug this problem I wanted to use netconsole
kernel module, unfortunately, because the Ethernet controller is emulated, it doesn't support polling and in effect netconsole:
[23463.961946] netconsole: local port 6665 [23463.961950] netconsole: local IP 10.10.12.10 [23463.961952] netconsole: interface eth0 [23463.961954] netconsole: remote port 6667 [23463.961956] netconsole: remote IP 10.10.12.1 [23463.961958] netconsole: remote ethernet address ff:ff:ff:ff:ff:ff [23463.961962] netconsole: eth0 doesn't support polling, aborting. [23463.961971] netconsole: cleaning up
Are there any alternatives to netconsole
not requiring physical access to host? I've got network syslog already configured.
Edit:
How is it possible to log all serial output coming from a particular DomU?
