Quickemu Problem

[Stephen P. Molnar]

I have just installed installed Quickemu v-6.1.4.

    quickget windows 11 ran as it should without any errors or warnings.
    However:
        (base) ***@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) ***@Abanormal:~/VM$

I am somewhat confused as:

    (base) ***@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.

Thanks in advance.

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"

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

--w------- 1 root root 0 19 mai 13:11 /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. :-)
