I don't know how to mount /srv/ltsp/vm-103-disk-0.vmdk
05:18
What could be the reason for this error I just scp the vmdk image to /srv/ltsp directory and from tried to build it using command ltsp image vm-103-disk-0.vmdk
05:20
<alkisg>
system_analyst: what's the output of: sudo fdisk -l /srv/ltsp/vm-103-disk-0.vmdk
05:20
It's supposed to be a raw image, so that command should be able to list its partitions
05:21

It's not a raw image then

What's the output of: file /srv/ltsp/vm-103-disk-0.vmdk
05:22
<system_analyst[m>
/srv/ltsp/vm-103-disk-0.vmdk: VMware4 disk image
05:22
<alkisg>
Right, that's a proprietary vmware disk image, it needs vmware to get mounted, it can't be mounted by simple losetup/mount linux commands that ltsp uses
05:22
Use a raw image instead of that one
05:23
<system_analyst[m>
okay... thanks for hint

root@compltsp:/srv/ltsp# sudo fdisk -l /srv/ltsp/ns3vm.raw... (full message at <https://libera.ems.host/_matrix/media/v3/download/libera.chat/b85d9759a848afdacb9677e630d3b48cb42a5835>)

At the disk creation dialog, select "VMDK" type and "Fixed size", not "Dynamically allocated".
07:12
In the partitioning step, make sure that the whole operating system goes in the first partition, without extra partitions for /boot etc.
07:12
Now you've used an extended partition, which ltsp can't handle
07:30
<system_analyst[m>
to craete the vm, i have running proxmox 7.1.4 . At the disk craetion dialog now i selected "raw" type. But I am sure whether it is dynamic or fixed size partition ? partition size selected is 60 GiB.
07:31
* I am not sure whether

system_analyst: it's fixed size. But you missed the second step, inside the installer, to select a simple disk partitioning

I want to distribute a java application for vehicle inspection using ltsp clients. You guys still recommend to stick with Mate for avoiding rendering issues with compositors? Or can I try to use the latest ubuntu/gnome/wayland combination in 22.04 and use the integrated rdp server in gnome for some tasks
14:57
<alkisg>
Trendzetter: if your graphics card have no issue with gnome, then of course ltsp won't have an issue either
