XenServer 7 has launched!

@BRRABill Replication uses export from one XS and pipe it to the import of another one. So in any case, it's import/export.

OK, when I get my second XS7 stood up, I will run a test from XO and let you know.

Still, seems very strange that everything is copying perfectly EXCEPT exporting from XS, especially given all the other people with issues.

I wonder why yours is working. "What's your secret????" I ask, wanting to hurry these exports the heck up!

If anyone else has XS7 set up already, if you get some time, export a small VM and see what speeds you get.

One thing I noticed today is that XS7 dropped the Server 2003 template. Not a huge deal, obviously.

Also, their XenTools no longer work. You have to use XenLegacy.

The xo-tools don't work for server 2003?

Or just don't work?

As ok that makes sense.

So it looks like it installs the PV stuff, just not the agent.

That might be the same as XS6.5 since they seem to have changed some stuff around in that arena.

@BRRABill Still have 6.5 in production here, but i just exported xoa disk in 5 minutes to a usb disk at my desk. 5min17s for 8GB
I then just exported it to my c:\ which is an ssd
same 8GB, 4m48s

What are you choosing for the network interface for xfer vm that xen uses?

My server has (4) 1GB ports. I have the management interface on one of those, by itself.

Also, are you doing a copy, backup, or export? Like an export in straight export?

And did you mean to ask what interface I have XO on? That is where it would export from. Or, through, rather.

I would LOVE to get this friggin' issue figured out.

I was exporting from Xencenter. I just shut the vm down and export.
I am talking bout this page

Network 0 is the default. However you have to either manually configure ip or have dhcp setup on your management network for that to work. I just set this to a vlan that i know dishes out dhcp, only for the xfer vm.

I was thinking perhaps you are hitting a bottleneck here if your settings force this go through a router that doesnt do Gb.
I hit about 400mbps (not constantly, but consistently) doing exports this way, during middle of the day. I could test when nobody is around later and hit a bit higher througput.

The machines I am exporting from/to are on the same switch.

I finally got iPerf to work on the XS host.

Here are the results. Pretty sure it's not the connection.

[ 3] local 10.0.4.30 port 55737 connected with 10.0.4.40 port 5001
[ ID] Interval Transfer Bandwidth

Definitely not

I got to thinking ... @olivier said that most of the stuff flows through XO. Like the copy is basically an export -> XO -> import ... I wonder if my XO instance isn't beefy enough.

We set it up minimal.

I'm going to test that after the July 4th holiday weekend.

As a point of reference...

I did a live migration tonight. So, basically the same sort of thing ... copying a VM from one XS to another.

It clipped along at about 65MBps. Took a little over 30 minutes to migrate about 110GB of data.

So, I don't think it is the hardware, or the network, or anything like that. It must truly be some bug in the exporting...

olivier

You mean a cross pool migration?

From one standalone to another.

olivier

That's a cross pool migration There is no such thing as a "standalone" server (despite XenCenter can say, the pool object is always here, from 1 to many hosts)
