Re: finding virtual server
thanks for the prompt response. I have no idea
regarding virutal servers. I upgraded the kernel using
aptitude and the server did not come up. This is a
colocation servers so i don't have physical access. I
update the system (including kernel) frewquently but
have never come accross my other debain servers.
So was wondering if the colo server is actually a
virtual server. Does virtual server have such issues
with kernel update ?
