Does the link here not already address this issue?

"I mentioned before that Syslog can forward messages to other hosts. Furthermore, it can forward Syslog messages to other hosts without writing a copy of the log to local disk. What this means is that a single XenServer or a pool of XenServers can send their log data to a "Syslog Aggregator". "

No, because further in the article, you will see...

"Certain logs will still continue to record Syslog on the host, so it may be desirable to edit /var/lib/syslog.conf and add comments to lines where a "-/var/log/some_filename" is specified as lines with "@x.x.x.x" dictate to forward to the Syslog aggregator."

And in XS7, that file has been totally replaced with the one I posted, which has different syntax.

@BRRABill Wouldn't the same essentially apply to the log file you have there?

Your file in /etc/rsyslog.d/xenserver.conf:

# Save boot messages also to boot.log
local7.*

Would be changed to:

# Save boot messages also to boot.log
local7.*      @your-syslog-ip
#local7.*

And in XS6.5 the syslog location is stored at

/etc/syslog.conf

Which still has the same flags.

@DustinB3403

Well, in 6.5, the syntax was as follows...

# Save boot messages also to boot.log
local7.*             @10.0.0.1
# local7.*         /var/log/boot.log

In this new version, it just puts the IP at the bottom.

@scottalanmiller mentioned, as I think you did as well, that I should just redirect /var/log somewhere else.

Being a little fresh in Linux partitioning, I most post a thread for help with that.

@BRRABill Why are you not commenting out the records as needed and adding them under each field in order?

You can edit the file (on XS7) with:

sudo nano /etc/rsyslog.d/xenserver.conf

Or on XS 6.5

sudo nano /etc/syslog.conf

I'll follow the setup on my lab tonight that is posted in the first link, and make all of the changes on XS6.5.

Then I'll see how it performs. from there I'll tear down my installation and repeat for XS7.

Here's one to watch from the Citrix forums: http://discussions.citrix.com/topic/379454-booting-xenserver-off-usb-safe/

P.S. Which one of you guys wrote this?

That was me.

Those guys know the nuts and bolts of XS, though they aren't real responsive to threads all the time.

On ML that would have have 500 posts already and been forked 6 times.
