<div class="moz-cite-prefix">1st20- 60Gb disk .. is preaty much .. <br>
2nd transfer is done via SCP that si a lil slower than any other
transfer but is more safer.<br>
3nd It depends on READ on the host where are the VMS .. if they
have other host working .. keep in mind that the machine share the
IO of that datastore. On perfect Datastone it sould be around 6ms
time to access data on HDD .. but on live datastore it my take a
lil more. <br>
My test was starting nonpersistent image with size 50GB on a SSD
drive it took around 4Mins and was not lunch via network, just
copy via scp .. on same drive.<br>

<div>Hi all,<br>
</div>
<div>I was just moving some VM's around as a prep for some
server maintenance, via live migration. I moved 3 VM's which
were all fairly small in size of 1GB - 3GB RAM and 20GB - 60GB
disk. I did the migrations 1 at a time. I was surprised at
how long the migrations took and also that each VM was pretty
much unusable during the migration. SSH sessions timed out
and websites were not able to be accessed. A VM with 3GB RAM
allocation took around 10 minutes to migrate.<br>
</div>

<div>Is this typical? Or do I maybe have some sort of issue on
my network or config? We run a dedicated 1000Mbps management
network for this type of thing, and all data storage access is
via separate 4x 1000Mbps bonded channels. I would have
expected 3GB of RAM data to be pretty quick. Probably < 1
min.<br>
</div>
<div><br>
</div>
<div>Are there any settings in ONE that should be tuned? I
don't seem to recall having an issue with migrations when I
was just running virt-manager/libvirt directly.<br>
</div>

</div>
<div>The last VM I have to move is a pretty important one and it
has 24GB RAM allocated. So I think it would be easier/quicker
to just shut the VM down, disable the host for maintenance,
and redeploy it. I'm hoping to avoid that.<br>

<div>Thanks for any advice,<br>
