#269453 — Quickemu Problem

From"Stephen P. Molnar" <s.molnar@sbcglobal.net>

SubjectQuickemu Problem
Message-ID<IFuDv-eduR-1@gated-at.bofh.it>
I have just installed installed Quickemu v-6.1.4.

     quickget windows 11 ran as it should without any errors or warnings.
     However:
         (base) comp@Abanormal:~/VM$ quickemu --vm windows-10.conf
     ~/VM ~/VM
     Quickemu 4.9.4 using /usr/bin/qemu-system-x86_64 v7.2.9
      - Host:     Debian GNU/Linux 12 (bookworm) running Linux 6.1 
(Abanormal)
      - CPU:      AMD FX(tm)-8320 Eight-Core Processor
      - CPU VM:   1 Socket(s), 2 Core(s), 2 Thread(s), 4G RAM
     ERROR! You have insufficient RAM to run windows in a VM
     (base) comp@Abanormal:~/VM$

I am somewhat confused as:

     (base) comp@Abanormal:~$ free -ght
                    total        used        free      shared 
buff/cache   available
         Mem:           7.7Gi       2.3Gi       225Mi 34Mi       
5.4Gi       5.3Gi
         Swap:          975Mi        50Mi       925Mi
          Total:         8.6Gi       2.4Gi       1.1Gi

The strange thing is that I have installed Windows 10 using QEMU/KVM 
virt-manager without any RAM problems at all.

Some guidance would be appreciated.

Thanks in advance.

I say: "without any **noted** RAM problems at all"

My guess is: 4Gb in the guest, requires much more 4Gb on the host.

Thank the mailinglist by sharing how you got beyond the hurdle.

All your RAM is being used as buffer/cache. Run the following command to
free up ram:

sudo sync && sh -c "/usr/bin/echo 1 > /proc/sys/vm/drop_caches"

The redirection won't work unless the person is already root—there was a
thread about this here just a few days ago. :-)
