The others lxdm and lighdm don't show as being available. How do I get the session to start properly?I do not see a problem with Fedora 37. The guest seems to run Ok. Perhaps a CentOS forum would be a better place for the question? Or, install Fedora Server and stop putzing around with the antique software RHEL and CentOS provides. My apologies if I mis-parsed something. JeffFedora 37 is the hostWhich Fedora variant?
Works for me also but I need CentOS 8 to run some legacy $$$ software.I just installed CentOS Stream cloud following the Fedora Server documentation (https://docs.fedoraproject.org/en-US/fedora-server/virtualization/vm-install-cloudimg-centos9/) and it works seamlessly.
What did you do exactly?
From virt-manager-> New virtual machine ->attached host ~/Downloads/CentOS-Stream-8-x86_64-latest-dvd1.iso->booted install
switched boot to VirtIO Disk and rebooted to blank screen. Initially the network was set to bridge which did not connect. Changed to virtual network and from a terminal boot updated CentOS 8. Added xinit and xterm and was able to install xfce4, switchdesk. Desktop now starts from a terminal boot with startx.
Your description is typical of a mismatched console configuration between virtual machine properties and guest OS configuration and independent of Fedora or any specific Fedora release.
Compared the CentOS 8 machine to the CentOS 9 machine. CentOS 8 uses 'Video Virtio' and 'Display Spice'. CentOS 9 uses 'Video VGA' and 'Display VNC'. Tried changes to the CentOS 8 machine to the same but get an error about an "unsupported configuration: 'spicevmc' not supported without spice graphics". Compared the --qemu/centos8.xml file with the --qemu/centos9.xml file. Understand some of the differences but not all.
