Actually, this issue is solved with a fresher ovmf package than the one shipped by default with Ubuntu 17.04 (0~20161202.7bbe0b3e-1).
This issue should be closed. ** Summary changed: - Cisco NX-OSv 9k crashes during boot with qemu 2.10.1(Debian 1:2.10.0+dfsg-2) + Cisco NX-OSv 9k crashes during boot with qemu 2.10.1(Debian 1:2.10.0+dfsg-2) and ovmf 0~20161202.7bbe0b3e-1 -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1732679 Title: Cisco NX-OSv 9k crashes during boot with qemu 2.10.1(Debian 1:2.10.0+dfsg-2) and ovmf 0~20161202.7bbe0b3e-1 Status in QEMU: New Bug description: Ubuntu 17.04 qemu 2.10.1(Debian 1:2.10.0+dfsg-2) gns3 2.0.3 NX-OSv 9k 7.0.3.I6.1 - No such issue with previous qemu 2.8.x - the issue does not seem to come from the debian packaging - the issue does not seem to come from GNS3 either, as confirmed by Jeremy Grossmann at https://github.com/GNS3/gns3-server/issues/1193#issuecomment-344240460 Either some parameters usage have changed (for instance -bios) (which would make qemu not backwards compatible) or there is an issue with qemu itself.
