@adriangabura This is a production server. This is also the only one we have on the cloud (OVH) for all our others hosts we use a private network behind our firewall and login via OpenVPN. But OVH we are struggling to come to a good design especially since version 8.3 now connect you to the web interface directly. How do we change port or block it?

@samuelolavo Shell only handles string values, to pass other types to xo-cli you need to encode them in JSON and use the json: prefix:
xo-cli resourceSet.create name=test-resource subjects=json:'["d301d9ea-9e22-4480-bf40-111111111111"]' objects=json:'["8fb06362-d8fe-598b-f819-11111111111111"]' shareByDefault=json:true

In essence, you can write any script you like in your VM that would be executed, test whatever you want in the database, and if it's OK, write a special key in the XenStore. XO will detect it and consider the backup health check done and working 🙂

What kind of backups are these? Incremental (delta), full, etc..? I think that'll help determining the issue, I had something similar once specifically with an incremental and was able to fix it. May not be related though since that was a while ago and on stable release channel for XOA.

Hmmmmm I need to look back through some of my old posts and notes but I had a similar issue with a VM with large number of disks. The disks themselves being big wasn't the issue, it was just having a huge number of them that eventually cased a problem. Ended up migrating by moving a single VHD and rebuilding things (the specific system didn't really "need" all the VHDs so it was an easy fix for me, wouldn't be the case here haha).

If you are trying to reduce the number of hosts though, why would migrating the VCSA help? If you're powering off a host then wouldn't you not need the VCSA to be running anyway? Or do you have more than 1 ESXi instance? Might be easiest to just migrate it to another ESXi host if that's the goal, since you won't need the VCSA once you fully move to XCP-ng (assuming you are doing so).

The only thing is to think on that script during a major update of xcp-ng to a newer version. Because after installation the autostart.service has to be implemted again.

I've had something similar in the past and if I recall correctly I had to go into the guest and disable it's network adapter, then make the change on the host, then re-enable the network adapter in the guest VM.

Might be worth a shot to see if that solves it.

I believe with the Citrix drivers though it doesn't happen.

You can create a valid VHD file with the command uuidgen 🙂

@Danp Ya, I normally restart the master first, but it was late and I was just trying to get them patched and restarted. I restarted 03 and everything came back up. Thanks!

If you want to put VHD file in an existing NFS SR, you need to indeed have an UUID type. Note that the SR file structure should NOT have any subfolder into it.

To generate an UUID, you can use uuidgen command.

Don't forget to always stay up to date to the latest commit as possible, because there's no support on older code for the version on Github 🙂

@MrNaz I recommend reading the XO blog; updates are published monthly.

NBD was introduced in the 5.76 release and the ability to enable in the Xen Orchestra UI was introduced in 5.79
https://xen-orchestra.com/blog/xen-orchestra-5-76/
https://xen-orchestra.com/blog/xen-orchestra-5-79/

Also enhancements were released in 5.81

Old thread i know but i will say that there is an issue with using VLAN.id 1
I am permitting all vlans end to end on my infrastructure and the only vlan that doesnt work is 1.
If i move the VM to another vlan then everything works.

I suppose the solution is to not use vlan.id 1 but thats terrible. all vlans are permissiable.

@elvintmp75

@elvintmp75 said in XO Proxy Comminuty edition Config Error:

I'm probably missing something obvious..any ideas?

Yes !

You forgot to read the instructions properly. It is clearly stated:
"This script is not supported or endorsed by Xen Orchestra. Any issue you may have, please report it first to this repository."

This means that this script/ install method is NOT made or supported by Vates (The guys behind Xen Orchestra / XCP-ng )

There may be errors in scripts and installs which you should report to the creator and not to this forum !

@olivierlambert Thank you and your team again for your commitment to this fantastic FOSS tool and for allowing me to build it myself!

I very much appreciate the personal touch of my issues being triaged by the CEO and Co-Founder. It's refreshing to see an executive officer stay in touch with their customer base.

Hi,
Indeed, only root user in the guest can read it Any user that can see the XAPI object will be able to read it
So I would say it's "reasonably safe", but it all depends on your global usage context and level of confidentiality you need.
