+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
+
+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.
+The configuration parameters are:

+The logs are:
+- [execution log](https://github.com/GNS3/gns3-server/files/1381651/qemu.log.txt)
+- [terminal log](https://github.com/GNS3/gns3-server/files/1381660/terminal.log.txt)
+
+With the latest qemu, I can boot:
+- Cisco IOSv 15.6(2)T
+- Cisco IOSv-L2 15.2(20170321:233949)
+- Cisco CSR 1000v 16.5.1b
+- Cisco ASAv 9.6(2)
+
+The major difference with NX-OSv 9k is the bios parameter: ```-bios /usr/share/ovmf/OVMF.fd```: 
+```
+ll /usr/share/ovmf/OVMF.fd
+-rw-r--r-- 1 root root 2097152 Dec  9  2016 /usr/share/ovmf/OVMF.fd
+```
+A normal boot log with qemu 2.8.1 is available [here](https://github.com/GNS3/gns3-server/files/1381729/terminal.log.2.8.txt)

+Highlighting the differences: qemu 2.8.1 on the left, qemu 2.10.1 on the right hand side with the same boot parameters
