I'm assuming you have read:
https://www.qubes-os.org/doc/split-gpg

The "Discussions" referenced at the bottom of that page are a good
guide.

As to the risks in storing all your keys in the same qube, there *is* a
danger, in that an attacker who gained access to a client qube would be
able to see your subkeys and therefore link identities.
Since the overhead in creating multiple pgp qubes is small, I would do 
that.


The reason I think it'd be beneficial to create one central domain is so 
it can be autostarted and handle most PGP operations, multiple vms 
wouldn't be very convenient, as well as limitations on memory usage, I 
wouldn't even think to autostart multiple PGP domains, but even in not 
doing so, my memory goes quick.


Should I utilize a dispvm as a middleman? One disposablevm shouldn't be 
too impactful on memory usage, and I could just copy documents around 
instead of multiple keys.

[qubes-users] Split PGP threat model questions

[qubes-users] Intel Optane?

2020-09-16 Thread Sandy Harris
I am likely to buy a machine soon for Qubes. One candidate would come
with 32G of optane & 512G PCIe SSD. I'm seeking advice on using optane
with Qubes.

Searching for optane on the Xen site gives no hits, a general search
for "qubes optane" gives a few but none that seem remarkably helpful.
"linux optane" gives a lot & I'm still working through them.

I'm not sure using the optane as a cache will work with Xen, or that
the payoff from putting cache in front of an SSD will be worthwhile.
Hence I'm inclined to just use the optane device as a fast boot drive,
which various sites say is possible. I'd put Xen, Qubes & likely Dom0
files there & everything else on the 512G device.

Is 32G enough for that? du -h on my current Kubuntu system shows 29G
for / and 18G of that is my home directory (which on the new system
will not be on the root drive) so it looks to me like it should be
fine. But how big is Qubes, assuming all VMs except perhaps Dom0 are
on a separate drive?
