Drive sharing
Closed this issue · 12 comments
Is there a way to enable drive sharing? Right now in KDE it doesn't seem to work.
shared-drives folder doesn't get created and Chansrv doesn't seem to exist.
That may have more to do w/ https://build.opensuse.org/package/show/Virtualization/hyper-v than what this package does. "hyper-v" is included during the installation process when the installing system is detected as Hyper-V. I'm not sure what provides the mechanism for such a thing, or what would be done w/in "Hyper-V Manager" to setup/enable it. Basically, seeing a working version of it - even in Windows - would be helpful in determining what's potentially missing.
Following the instructions for Ubuntu 20.04 yields a working shared-drive fuse mount folder in home directory containing the shared drives.
I believe I've seen that one before. I don't see anything (obvious) in https://raw.githubusercontent.com/Hinara/linux-vm-tools/ubuntu20-04/ubuntu/20.04/install.sh which is missing in openSUSE. But I'm testing a 'Quick Create' Ubuntu 20.04 VM and following those steps now, I'll see if that results in something positive.
Putting aside the weird fact that "Ubuntu 20.04.4 LTS" has to be "Save"d, then started back up for "Enhanced Session" to work - I do see a 'shared-drives' folder. It's empty - so I'm not exactly clear at this point what it's for? Copy/paste from Win11 desktop to the Ubuntu VM does work (doesn't work in openSUSE, but maybe it's related to this?).
This is the only hv_ difference between the two:
Ubuntu: hv_vmbus 122880 8 hv_balloon,hv_utils,hv_netvsc,hid_hyperv,hv_storvsc,hyperv_keyboard,hv_sock,hyperv_fb
openSUSE: hv_vmbus 151552 8 hv_balloon,hv_utils,hv_netvsc,hid_hyperv,hv_storvsc,hyperv_keyboard,hyperv_drm,hv_sockSo maybe it boils down to something between hyperv_drm and hyperv_fb?
Steps to reproduce shared drive working in Windows 10 21H2 Hyper-V:
- Create a VM named ubuntu, Gen 2 with all Integration services enabled
- Install ubuntu 20.04.4 with auto login disabled, update and reboot after installation
- Verify that there is no shared-drives folder
- Run the following commands:
wget https://raw.githubusercontent.com/Hinara/linux-vm-tools/ubuntu20-04/ubuntu/20.04/install.sh
chmod +x install.sh
sudo ./install.sh
- Reboot ubuntu
- Run the following commands (it wasn't necesarry for me):
sudo ./install.sh
- Shutdown ubuntu
- Close Virtual Machine Connection window
- Run in powershell as admin:
Set-VM -VMName "ubuntu" -EnhancedSessionTransportType HvSocket - To verify that it was set correctly run
(Get-VM -VMName "ubuntu").EnhancedSessionTransportType, it should reportHvSocket - Start VM
- Select drives to share
- See that shared-drive folder exists
and has the shared drives as it's content
and drives show their contents:
- Try reading and writing to a drive
- Read:
- Write:
- Observe results in windows
- mounts in ubuntu vm

I'm so used to just picking a display resolution when opening the VM console I didn't think to look @ "Show Options", "Local Resources", "Local devices and resources", "More...", "Drives".
That all appears to work for me w/ the Quick Create Ubuntu VM.
I copied over sesman.ini & xrdp.ini from the Ubuntu VM but it didn't make any difference ; a vimdiff didn't show any glaring differences to begin with (and IIRC, I kinda picked apart that Ubuntu setup - and this one - initially when putting this together).
It's also quite possible that SUSE's xrdp package doesn't support fuse:
[ 78s] xrdp will be compiled with:
[ 78s]
[ 78s] mp3lame no
[ 78s] opus no
[ 78s] fdkaac no
[ 78s] jpeg no
[ 78s] turbo jpeg no
[ 78s] rfxcodec yes
[ 78s] painter yes
[ 78s] pixman no
[ 78s] fuse no
[ 78s] ipv6 yes
[ 78s] ipv6only no
[ 78s] vsock yes
[ 78s] auth mechanism PAM
[ 78s] debug no
[ 78s] rdpsndaudin no
In the somewhat near future, I'll branch X11:RemoteDesktop/xrdp and try to rebuild with --enable-fuse and cross my fingers that's all it is ;)
That was it.
Thankfully, in terms of [re]building xrdp w/ fuse support - it wasn't too involved:

%installI suppose we have 1-3 options, depending on your interest level in the fix:
- You can branch
X11:RemoteDesktop/xrdpyourself in OBS and make those simple changes. - I can check this updated xrdp version into my home:sbradnick:branches:X11:RemoteDesktop project and you can add it to your repo list whereever you're using SUSE (just let me know which arch/flavor you'd need builds for).
- I can submit an SR to the devel project and we can attempt to get this in the mainline xrdp package.
I'm fine w/ all 3 options 👍
I think it would be for the best to submit it to the devel project so it can trickle down to other users, rather than to have a "one off".
Since you found the solution you could submit it to the devel package, or if you don't have the time I'll be happy to try (although I'm not well versed in obs submissions).
PS. Would it be possible to change the order of [Xorg] and [Xvnc] session type in xrdp.ini (aka to put the Xorg session as the default session) since, and I may be wrong on this, Xvnc performance is not up to par to Xorg (at least in nested opensuse host -> win 10 vm -> opensuse vm in win 10 vm).
I could be completely off base here though.
Very good :) ==> https://build.opensuse.org/request/show/964905 ; maybe the maintainer(s) will come back and say 'this is the reason we don't' - but we'll have to see.
I did notice Ubuntu has them in a different order in xrdp.ini ; that wasn't a conscious decision on my part - and I believe it comes from the the xrdp.ini file used in the base package. I do [re?]include it in mine, so I suppose I could flip them there. But I have no idea if that makes a difference.
https://github.com/neutrinolabs/xrdp/blob/devel/xrdp/xrdp.ini.in shows [Xorg] then [Xvnc] ; if you swap them, is there a noticable difference?
Xvnc seems to be a bit sluggish, like it's running at 30-40 fps and having standard vnc hitches, while Xorg feels more fluid and has a lower cpu impact (20% lower in my case).
However, I'm not sure how it would work with Gnome since they seem to be mainly targeting Wayland and not Xorg (maybe there would be some regressions).
I've switched them up in the xrdp.ini file this package is providing and will push it forward. Also, 964905 was accepted into the devel package and is currently testing in Factory.
Excellent, thank you for your time and effort.
