Hi, am Ajay Kumar.

I am trying to create a virtual machine on the remote host (where libvirt 5.8.0) was installed using a virtual machine manager which are running on the local ubuntu machine.

The specification of my remote host are:

Hypervisor: KVM

The below error is propagating when I am trying to install KVM-VMI (https://github.com/KVM-VMI/kvm-vmi/tree/kvmi) with modified QEMU, and there is a modified QEMU involved, in /usr/local/bin/qemu-system-x86_64.

The below particular error propagating when I am trying to create a virtual machine using VMM gui (virt-manager).

Unable to complete install: 'internal error: process exited while connecting to monitor:
(process:7400): GLib-WARNING **: 18:19:45.044: ../../../../glib/gmem.c:489: custom memory allocation vtable not supported
2019-09-30T18:19:45.046714Z qemu-system-x86_64: -msg timestamp=on: Unsupported machine type
