Domain qube1 has failed to start: Not enough memory to start domain 'qube1'

[mike]

Hi All,

Sometimes I cannot start any qube with a popup message as in Subject, or when I run qvm-start I get:

$ qvm-start qube1
Not enough memory to start domain 'qube1'

I have 16GB RAM and I am running just a few qubes, so there's definitely no real memory issue.

How can I investigate memory issues in Qubes?
How can I see how much memory all qubes are using, how much is available etc?

Thanks,
Mike

You can use xentop to see what's happened to your memory.

Mine shows approx 4Gb in dom0, 2Gb in a couple of web VMs, 1.5Gb in my
mail VM and in sys-firewall, plus much smaller amounts in other sys VMs.
I have approx. 2Gb free in my 16Gb laptop at present.

Mike.
