simple qemu command not working

[haris iqbal]

Hi,

I am trying to install ubuntu in one of the qcow2 images I have
created, using the below command

    sudo qemu-system-x86_64 -enable-kvm -nographic -smp 8 -m 8G -cpu
qemu64 -cdrom ubuntu-19.10-live-server-amd64.iso -boot d
ubuntu-19.10-live-server-amd64.qcow2

First it spits out a warning, and then just hangs at "Initializing gfx code...".

    qemu-system-x86_64: warning: host doesn't support requested

    Initializing gfx code...

I have searched a lot and got a number of solutions and possible
problems but none worked.

1) Have tried with Ubuntu 20 also, but same error.

2) VT-x not enabled.

It is enabled, `lscpu` shows

    Virtualization:                  VT-x
    Hypervisor vendor:               KVM
    Flags: .. vmx ..

3) Tried with `-cpu qemu64`. Did not work

4) used `qemu-system-i386` instead of `qemu-system-x86_64`. But that
fails with a different error

    This kernel requires an x86-64 CPU, but only detected an i686 CPU.
    Unable to boot - please use a kernel appropriate for your CPU.

5) I have asked the same question online, but no answers.
https://stackoverflow.com/questions/61864520/qemu-installating-ubuntu-through-iso-gets-stuck-shows-svm-cpu-bit-warning

6) Have tried without the -nographics option, same story.

7) I did find out that the "SVM" CPU bit corresponds to "AMD Secure
Virtual Machine", which confused me since my CPU is Haswell.

The host system on which I am running this command is an ubuntu.
I have tried this on 2 separate ubuntu machines, one running on
virtualbox as a VM with host OS windows 10.
The other also running on a virtualized hypervisor (not sure which
one), as a VM.

Can someone point out what the problem is, and what is the solution.
