Seems interesting thanks, sometimes I wondered if there was any way to
reduce the burden to have all these sysVMs always working.

But for most people, me included, changing a firewall without fully
understanding it may be dangerous.  We are dealing with some core element
of Qubes security.

So better to wait for some official, pre-installed and supported version of
it, if any.

[qubes-users] Re: New qubes user question/issue: firewall VM consuming unexpected amount of RAM

[J. Eppler]

Hello, 

all VM's in Qubes consume a large amount of memory by default. You can 
restrict your firewall VM to 1 GB or less. 
You can restrict the memory consummtion under 'Right click -> VM Settings 
-> Advanced' to Max. Memory ~1024 MB or less. 

There is also a Unikernel solution. Unikernels are special purpose 
operating systems. Thomas Leonard created a Unikernel firewall for Qubes OS 
which runs perfectly fine with 30 MB of RAM. 

You will find resources on how to do it here:
