I'm not sure how much this is related but I see something similar on our
setup.

Our setup is CentOS 5 running both on Dom0 and DomU. The DomU's have at
least two separate IP addresses assigned to each one of them (statically for
now, until I get to move to virtual rack and VIP's). The machine setup
process destroys the xen image and re-builds it. In the process it reboots
the Xen guest a couple of times.

I see on one of the Xen servers that sometimes (after too many DomU
reboots?) the second IP address on the re-created DomU just stops
responding. I can access it from Dom0, and I can even see packets from the
outside world reach the Xen Dom0, but can't talk to that second address from
outside. The first IP address works fine.

Have you tried to reboot the VMware host?

Below is the script (with minor changes). You should also look at the
"rsnapshot" - http://www.rsnapshot.org/ which does the same (with much
more options) in perl.

you mean you utilize something like rsnapshot ?

this is a great solution. however it is not a real snapshot solution like
LVM (version whatever)
this is neither 'create snapshot in zero time' nor 'in zero space', contrary
to LVM.

total disk space is at least twice the size of your data
in LVM is only once + size of changes.

This is not the case with my suggestion. The hard link is between
"snapshots", there is no hard link to the original files.

I forgot to add (it seems trivial) that the pseudo "snapshots" are
mounted read-only.

using hard links as snapshot is works only if you ensure people do not open
new files with append mode.
if they do, they will modify your file as well as it's snapshot ...

There are also "packaged" scripts that do something like this. I
personally use rsnapshot, there are a few others.

You don't want many snapshots because of the heavy load penalty (each
write is multiplied by the number of snapshots).

If you have enough disk space you can create "pseudo" snapshots by
using hardlinks between the snapshots so only changed file takes space.
It really depends on the file size distribution - few large files that
change constantly will defeat this concept, while many small files is
ideal for this scenario.

I use this approach and keep more than 60 "snapshots" of 350 GB disk
on a 700 GB disk.

The whole process is very simple:
Initiation: copy the whole disk (or an LVM snapshot of it) to the
destination disk in a SUBDIRECTORY (eg `cp -a').

  For each snapshot:
1. Check the size left on the "snapshot" disk and remove old
   "snapshot"s until you have predefined minimum space.
2. Copy the subdir (hardlink only) to a new subdir (I use `cp -al').
3. Create an LVM snapshot of the original system.
4. Sync the copied subdir with the real LVM snapshot (`rsync').
5. Remove the LVM snapshot.

I can send you a script we use on our system but most of it is our
specific details.

virtual machines losing touch with LAN on reboot?

[Ira Abramov]

one of my clients started playing around with vitual machine images on
VMware player, VMware server (free edition) and Virtualbox. we tried
hosting ready-made images from the net as well as local installs of
Ubuntu 7.10, 8.04 and Fedora8 with an XPO machine as host. in all cases
we add a few packages (not upgrading kernel), reboot and find that we
have no real LAN connection. ethtool shows link is up but no DHCP
replies are coming. I bumped into Network-Manager there and could not
figure out where it stores the configs so on the Ubuntu I ust removed it
(and saw the eth definition show up in /etc/network/interfaces instead,
yay!), but a reboot left me still with no LAN connection.

I thought it was the VMware tools I compiled, but the same happend on
Virtualbox! and both before and after the reboot, it was the same
pcnet32 driver, taking it out and insmodding again made no difference.

then I accidentaly discovered booting at Single-luser mode left me with
working LAN and dhcp, which worked if I then continued to runlevel 2
(Ubuntu), but booting to runlevel2 the normal way left me disconnected
again. this is REPEATABLE.

till I find a solution, I told the guy to boot to "recovery mode" and
just hit "ctrl-D" at the single-user-mode prompt, and then LAN works.

anyone got an explanation for this extremely odd behvior?!

problem is that the CAD tools running here dictate that we stick to
RHEL4 (damn you, Cadence! how hard is it to support RHEL5?!), and
snapshots are problematic at 2.6.9 (some problems were solved only at
2.6.16)

instability in the old kernels, multiple snapshots mean multiple COWs
(which zumastor is built to solve). people here wanted hourly0,1,2 and
daily0,1,2 AND weekly0,1,2. that means 9 growing snapshots at any given
moment, and that is one very serious disk handicap. snapshots in LVM2 are
not really designed for that, they were mainly meant to be for hot
backups of file systems, so you can freeze the FS just long enough to
snap the state to a tarball and remove the snapshot.

Re: controlling CPU's fan speed

Hi,

Thanks for the reply.
I didn't mentioned it verbosely but its a desktop machine, not a laptop.
I'm not sure it means too much but I can add that when powering up the
machine I do hear the FAN running at high speed but when it gets to OS
loading phase it gets calmed down - for good until the next reboot. 
I would not want to cycle down the CPU in order to lower the heat. Not
that I think it'll help: when the machine gets loaded (and even some
sites when surfing via firefox cause lots of load) it gets warm very
quickly (so cycling CPU down in advance wont "gather coldness" for
tougher times. I think).

Re: controlling CPU's fan speed

[Alex Alexander]

Hey

On my old HP nc8000 the fan speed was inaccessible through the OS. It would
power up (and make a lot of noise) only on really high loads and the laptop
would still get pretty hot. I had to use the powersaved daemon to
(automatically) throttle the CPU freq when not needed.

AFAIK this is the correct way to keep the temp down on laptops. Temps > 50c
are normal on high load situations. My current Dell (xps m1530) could boil
an egg when running 100%.

One more thing. After 3 years of continuous usage, my nc8000 cpu's airflow
got blocked by a big solid pile of dirt. This resulted in extremely high
temps (even the keyboard was burning). Don't forget to check yours for dust
and dirt!
