Hello,
I tried to quickly test the OVA import with a CentOS 7 OVA file that I
downloaded from:
https://dlconusc1.linuxvmimages.com/046389e06777452db2ccf9a32efa3760:dldatac/VirtualBox/C/7/CentOS_7.9.2009_VBM.zip
6785cb04dc5e7ab5a28ec139f631dfc8aeb8a6278c5fc66e1e7030d3f5a83b18
/var/lib/vz/import/CentOS_7.9.2009_VBM_LinuxVMImages.COM.ova
After enabling the "import" content type on my local directory storage,
the ova file shows up in the import section of the storage.
Upon clicking "Import" in the web UI the "Import Guest" dialog opens
along with an error message stating:
XPath error : Undefined namespace prefix at
/usr/share/perl5/PVE/GuestImport/OVF.pm line 239. (500)
Closing the error message also closes the import dialog, preventing me
from importing.
The same thing happens with this ArcoLinux OVA file:
https://master.dl.sourceforge.net/project/linuxovafiles/GUI/ArcoLinux-vm.ova?viasf=1
to /var/lib/vz/import/ArcoLinux-vm.ova
2b353ac59598bac24d4cf0721e367935d00178a31d84e09c94425bdee3dab6a1
/var/lib/vz/import/ArcoLinux-vm.ova
