<div class="moz-cite-prefix">Of coz. But serving virtual disks over
gigabit ethernet is generally bad idea too.<br>
And stable 70 megabytes per second are much better than unstable
100. Also I think that you don't need to limit iops, just
throughput.<br>

<div>There's issue with NFS: if you try to send
over it more than network can deal with
(100-120 MBps for 1-gigabit), it imposes
several-second pauses, which are being
interpreted like hardware errors. These bursts
may be just few seconds long to trigger issue.<br>
<br>
You can try to limit bandwidth in virtual HDD
config to something like 60-70 MBps. This
should be enough for 1-gigabit network.<br>
<br>
But my opinion is that it's better to switch
to iSCSI.<br>

I wonder why I

I said before,
with Ubuntu,
CentOS, Windows 7
and 2012, and work
fine! <br>

Not of all have huge
big files or a lot

they stand solid!<br>

But when require a lot
access and deal with
big files, here's came
the devil! The VM just
get IO error and die
before 2 or 3 days...<br>
</div>
On both physical
servers, not hight load.
I check with HTOP and
TOP as well.<br>
</div>
iostat doesn't show
nothing wrong.<br>
</div>
In side the VM, a lot I/O
error from time to time...<br>
</div>
IO goes high endeed, but is so
expect because I am using
imapsync to sync mails to old
server to Zimbra Mail
Server...<br>
</div>
But I do not expect the VM die
with IO errors!<br>

It's so frustrating... :(<br>

I suppose it's bad
idea to run KVM
machines via NFS: it
may produce big enough
delays under high
loads, which may look
like timeouts on
client side.<br>
If you want some
network storage, iSCSI
can be better chiose.<br>
