Ashijeet: I've been testing my branch and it seems installing Fedora/CentOS to a VMDK image is broken with your patches applied. Both guest and QEMU are responsive, but the installing of packages stops to make any progress at some point: Installing rootfiles.noarch (317/318) Installing langpacks-en.noarch (318/318) Performing post-installation setup tasks Configuring fedora-release.noarch Configuring filesystem.x86_64 Configuring GeoIP-GeoLite-data.noarch Configuring python3.x86_64 Configuring fedora-logos.x86_64 Configuring kernel-core.x86_64 # hang here Can you reproduce this on your machine? My command line is something like this: qemu-system-x86_64 -enable-kvm -cpu host -m 1G -qmp unix:/home/fam/.q/qemu-8DOC9EF4/qmp,server,nowait -name 8DOC9EF4 -netdev user,id=vnet,hostfwd=:0.0.0.0:10022-:22 -device virtio-net-pci,netdev=vnet -drive file=/var/tmp/test2.vmdk,if=none,id=drive-1,cache=none,aio=native -device virtio-blk-pci,drive=drive-1 -cdrom /stor/iso/CentOS-6.9-x86_64-minimal.iso -pidfile /home/fam/.q/qemu-8DOC9EF4/pid qemu.git master doesn't have this problem. So I'll drop this series from the pull request until it is resolved. Fam
