Cannot export VM in .ova file
-
Dear,
with a brand-new 8.2 xcp-ng server installation I was able to export ova from XCP-NG Center.
After upgrading it with latest patches (yum update) I'm not able to to export back ova.
I've done this test both on my production server and also installing it in a new system from scratch.I've tried using both DHCP and static IP. no luck.
Thanks in advance for any feedback.
The log reports is the following:

I wouldn't rely on XCP-ng Center for that. Xen Orchestra will have OVA export in the April release. VMDK export is already there
-
@olivierlambert thanks, OVA export in april will be a very great feature that complitely allow me to forget xcp-ng center
-
Indeed, we are close to finish it, maybe even March release Hang on!
- about a year later

@olivierlambert
and how to export the xo appliance with xo? -
Like any other VM?

@olivierlambert
playing arround since hours to migrate my xcp-ng (running on my HP Gen8 Microserver) to a bigger SSD.
cloning the disk with clonezille wasnt successfull so i decide to start from scratch.- Exporting xo with xcp-ng center -> pain in the ass
- ex and importing vhd manually -> same pain in the ..
i am working since years with vmware and proxmox but this one was challenge ... such a "simple" think
now i have created a new vhd ... and copy the old xo vhd over it ... rescan .. worksi couldnt find a working tuto for doing this the right way ..
br,
rowie -
Maybe your question was not clear, you asked to export XO with XO, you didn't talk about XCP-ng at all It was a typo then, you meant XCP-ng?
-
@olivierlambert
yes, xcp-ng! sorry for confusingxcp-ng Center isnt working great in such things right?
-
XCP-ng Center isn't an officially supported client for XCP-ng in the first place, as per https://docs.xcp-ng.org/management/
-
ah, ok. that explains a lot!
What is the best way to migrate xcp-ng to a larger hard drive?? -
Depends a lot on what you have available. IMHO, I consider the system as disposable, since you can export the metadata, reinstall and import the metadata again. Or backup your VM, reinstall, restore. Or migrate out to another host, reinstall, re-migrate the VMs.
So many possibilities, that all depends on your setup.
