Xen & Windows Server 2008 R2 x64

I may be reading that wrong but it appears to say that if you live migrate the machine it hangs when it reaches the other server but if you shutdown and bring it up it [b]still[/b] hangs! Thus it appears to be quite consistent and always hangs. I suspect that may not be quite what you meant?

I meant that you should repeat your yum install command and add --disableplugin-fastestmirror to it - it was not a complete command!

Re: Server hangs up every day with messages like "soft lockup - CPU#0 stuck for 10s"

But that's completely different to the problem you had before? Before you were getting soft lockup messages with stack traces. This one looks like a power off/unplanned reboot - is that correct? So was it updating that changed the symptoms or has it always been a mixture of the two? There are some s...

Most likely a lack of memory on the machine but you could try using yum --disableplugin=fastestmirror install ...

Re: newbie! 403 error forbidden

If it's just the top level directory that's had its ownership changed then running

[code]
rpm --setperms httpd
[/code]

might fix it by resetting the permissions on the various files owned by the httpd package back to their default values.

Is just a warning but can be eliminated by editing /etc/security/limits.conf and adding a line e.g.

Re: Server hangs up every day with messages like "soft lockup - CPU#0 stuck for 10s"

Ok, you're now up to date which at least eliminates known bugs! Can you look in /var/log/messages and find where the latest batch of problems started and place an excerpt of the messages around this point on pastebin? Say a couple of minutes prior to the first lockup message and then the _first_ loc...

Re: Server hangs up every day with messages like "soft lockup - CPU#0 stuck for 10s"

First thing to try would be to update to the latest level of software - what you are running now - 2.6.18-194.26.1.el5 - is quite old. That is CentOS 5.4 and the latest is 5.6. No idea if your problem is fixed in the meantime but it is worth a shot. The messages you posted, are those the first ones ...

Re: Syncing time, Windows Server, Workstations dual booting Windows 7/CentOS 5.5

Well I'd do it the other way around. CMOS time is notoriously unreliable and tends to drift by seconds or even minutes a day. You can easily tell the Windows time service to update from an SNTP source and run an ntp daemon on your CentOS machine that will sync with the standard CentOS ntp servers on...

Yes, that's not correct. You need to use

[code]
su - root
[/code]

See the '-' sign in there, that means to source root's environment and remove the current user's. It sets things like $HOME correctly.
