[AMD Official Use Only - General] Hi Rajesh,
Thanks for the update. I'm glad you were able to get it worked out. Ideally we wouldn't *require* sudo access but for KVM in general I think it is going to highly depend on how the system was setup and there are some things that packer won't be able to get around in some setups. -Matt From: Rajesh Shashi Kumar via gem5-users <gem5-users@gem5.org> Sent: Tuesday, December 6, 2022 10:00 AM To: gem5 users mailing list <gem5-users@gem5.org> Cc: Rajesh Shashi Kumar <reachrajesh...@gmail.com> Subject: [gem5-users] Re: KVM error while trying to build disk-image for GPU-FS Caution: This message originated from an External Source. Use proper caution when opening attachments, clicking links, or responding. Update: I was earlier running this on a shared server that I did not have sudo access on (not that I actually used sudo in the build process). But the build seems to work fine on my local machine with the following dependencies satisfied. I read on other forums that the KVM: Permission denied issue occurs due to /dev/kvm permission issues. sudo apt install qemu-kvm qemu virt-manager virt-viewer libvirt-clients libvirt-daemon-system bridge-utils virtinst libvirt-daemon Thank you for your time!
