BTW you could also use dmidecode (in dom0):
$ sudo dmidecode|grep 'Range Size'

If you need it, you can switch it back by removing dom0_mem parameters
from /etc/default/grub, rebuilding grub config:

$ sudo grub2-mkconfig -o /boot/grub2/grub.conf

and rebooting.

ah yes xlinfo, i learned of this command when trying to find a way to show how 
much memory the system recognizes installed.

Its still confusing to me to figure  exactly how much ram i have available to 
use for vms. or if all memory is being given back when shutting things down.

In 3.0 all memory was loaded by dom0.  So I would just watch the qubes-manager 
and make sure missing memory from dom0 matched up to total of the vms.  But 
since 3.1 though dom0 is limited to 4gb so accounting for all the memory 
manually that way is not possible anymore.

I figure I need at least 1700mbs for dom0 before things start crashing and I 
just consider my available memory w/e is extra in dom0.

this because I don't have alot of ram and never have more then 4 available 
anyways.

Re: [qubes-users] Available memory

2016-09-29 Thread York Keyser

Hi,

I'm answering my question by myself because I think I found a solution 
for my question. The command "xl info" show at least the virtual memory, 
but I think it would be a nice thing at the Qubes VM Manager to show the 
hardware info global wide ;)


Regards York

what I do is show inactive vms and keep qubes-manager open at all time and look 
for triangles to see if there is a problem in a vm to shut it down when needed. 
  Like Justin Cooper(Salute) for Hillary's server haha unplug it(Shut it down) 
for a second and restart it see if it persists.

I never saw in a Campaign,  a candidate say go to my website and we will be 
fact checking everything in real time haha.  Pioneer.

add cpu and hdd activity and all that as well lol.  xentop is another way to 
only show only activity for each vm but I find it more accurate then 
qubes-manager.

Before 3.1 I use to just add all the ram up from all the vms with a calculator, 
 but after 3.1 they changed the way how dom0 handles ram,  probaby for a very 
good reason,  but there is now now way to tell for me when what vm is giving 
back ram or not.  or how much total being used or free.

Last I heard, there isn't an easy way to see the total available RAM in
all VM's.  Maybe some progress happened there and I haven't heard?  It
would certainly be a useful feature.
