Proper way of assigning a shortcut to run a script in a VM

[empty0]

I am aware of assigning a shortcut normally in XFCE (Keyboard >> Application Shortcuts >> + Add >> command: qvm-run -q -- VM command …) that will work. But it takes considerabily more time to run the script than if executed the command in the VM terminal.

I’m thinking of a command to run in dom0 that passes key press to the VM instead, and then utilize e.g. xbindkeys in the VM to bind the shortcut normally. I searched for the command to run in dom0 that would do so, but couldn’t find…

Note: I do want this to function without having a window of the VM running.

Then, how would you specify which VM is the target?

In Qubes OS only the focused window (and it’s VM) will get the keys you pressed. Whithout such, all keyspress is handled by dom0 → GOTO qvm-run

An easier way to shave off quite a lot of latency is to use qrexec-client directly instead of through the qvm-run wrapper:

Fast dom0 -> Qube commands

Hello, I am searching the fastest way to execute a command from Dom0 to a Qube with the following requirements: exit code is important (I must know the command fail) stdout / stderr is irrelevant should still be secure should be fast Right now on my machine, this invocation is 180~270ms: qvm-run disp777 /bin/true I am wondering if I can use directly qrexec-client as I know it is very much faster (this is 10~20ms): qrexec-client -tT -d deb-dvm 'user:exec /bin/true' > /dev/null 2>&1 But is…

If you don’t care about the command’s stdout / stderr / exit status, you can even use qrexec-client -e to just fire it off asynchronously (which has no qvm-run equivalent), like here.
