On CentOS 7 server, after installing KVM, i connected to server using Virt Manager. During VM creation, i get following error
libvirt.libvirtError: internal error: qemu unexpectedly closed the monitor: 2021-02-01T18:09:38.214356Z qemu-kvm: -chardev pty,id=charserial0: Failed to create chardev
To fix this, edit file
vi /etc/fstab
Find
devpts /dev/pts devpts defaults 0 0
Replace with
devpts /dev/pts devpts gid=5,mode=620 0 0
Reboot the server. After reboot, VM creation will work properly.
