Hello,
I had a I/O error this morning affecting a node and randomly some VEs.
In Host System
[root@laxvps ~]# ls -ls
ls > ls: reading directory .: Input/output error
Inside VEs
Sometimes everything works fine and sometimes get the same HN error
I have checked user_beancounters and there are no errors

Its a storage layer problem and not isolated/due to a VE. I would set up netconsole (check wiki), and you can view your server's dmesg output even after the problem occurs.
What is happening is the system cannot even read the dmesg binary. If your kernel is exporting its ring buffer over the network, I think you can see whats going on. Likely, you will see some error on /dev/hdX, /dev/sdX, etc.
When the problem occurs, you have no choice but to reboot the node, correct? Are there any messages on the local console?

I'll setup the netconsole now, but it really seems to be with the controller.
When it happens:
1 - laxvps kernel: journal commit I/O error
2 - FS(Ext3) - read-only
3 - Some files are accessible, others don't
