Ubuntu Installation on Qemu shows Black Screen - Without Graphics

us flag

I'm using a KVM-based virtual machine on OpenStack, and I'm trying to boot a virtual machine on that. I have installed QEMU emulator version 4.2.1

I tried to build a vistual machine using this command:

qemu-system-x86_64 -boot d -cdrom ubuntu-18.04.5-live-server-amd64.iso -m 4096 -hda sheepdog:Test

I don't have any graphics, so I have tried the -nographic and -curses options for booting my VM but none of them works and only shows me a black screen.

I can't understand what the problem is, and I don't know what else to try.

BTW, seeing sheepdog there - sheepdog features are not built into Ubunuts qemu. For the UI I'd expect -curses to be fine, but that depends to some extend how you connect there. You'd usually consider to have it spawn a VNC or Spice connection if you need UI, and then connect to that separately. You could for example add "-vnc :4" and can connect to port 5904 with a vnc client. Furthermore I wanted to mention that this (depending on the version) isn't HW accelerated - consider to add -enable-kvm.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
