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.
How is it possible to log all serial output coming from a particular DomU?
