Thank you @olivierlambert & @Danp . Greatly appreciate your assistance!

@olivierlambert Thank you, I've changed the settings on b2 to "Keep all versions of the file (default)".

I can confirm it's now working. Thank You! Health page loads fine w/ the latest commit.

@florent Thank you for your assistance!

I'm also running into this issue after upgrading to the latest build (Xen Orchestra, commit d3077):

Hi,

I'm trying to change the MTU but keep getting "The uuid you supplied was invalid" error (see screenshot below). I'm copying the network uuid to use in the cli command. Any thoughts/recommendations?

Thx,

SW

@Darkbeldin Thank you, I looked at the SMlog and searched for this snapshot where I only saw activity back in March 27 and yesterday (April 26). See attachment.
smlog.txt

@olivierlambert Thank you! How do I add a new disk and ensure it doesn't use the same device id (/dev/xvdc) as that is currently used by the VM? The VM currently sees this:

/dev/xvda1 94G 18G 76G 19% /
/dev/xvdb1 12G 4.4G 7.7G 37% /var/lib
/dev/xvdc1 80G 23G 58G 28% /var/www
/dev/xvdd1 200G 54G 147G 27% /Emails

What does "Import VDI content" and "Export VDI content" do? Just trying to see if I can copy this snapshot and then attach it to the VM:

Thank You,

SW

After about 30 minutes, the list of disks changed and now it shows the following:

@Andrew Thank you that sounds perfect!

@tjkreidl Thank you for your assistance and recommendation!

Hi,

Hoping someone here can help me with if I can create a pool from the below hosts without negatively impacting VM stability / live migrations. I read the docs but it seems the doc are missing a link to "see Hosts and resource pools".

Here are my current hosts which are all currently not in a pool:

Host 1: Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
Host 2: Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
Host 3: Intel(R) Xeon(R) Gold 6132 CPU @ 2.60GHz
Host 4: Intel(R) Xeon(R) Gold 6132 CPU @ 2.60GHz
Host 5: Intel(R) Xeon(R) CPU E5-2650 0 @ 2.00GHz
Host 6: Intel(R) Xeon(R) CPU E5-2650 0 @ 2.00GHz

Shared NFS storage will be either TrueNAS or Synology depending on which storage offers best performance and VM reliability.

The goal is to build this pool for HA or have two different pools each setup as HA.

Thank You,

SW

@olivierlambert Thank You Oliver! I've been meaning to move these 2 VMs to newer servers running latest XCP-ng. The issue in trying to move them is the migration takes so long as the VMs are very large.

Any recommendations on how best to move large VMs that use a mix of local and network storage to a new XCP-ng?

Hi,

I'm running an older version of XCP-ng (v 8.0.1) which I'm trying to figure out what is causing the Dom0 high memory usage:

@Darkbeldin Thank you! I was able to get in after 1st logging to the xen-orchestra.com website, updating my profile, and then clicking on support from that portal.

Here is the Ticket#775709.

Look forward to your update!
