qemu-0.11.0-patches-for-gns3

Patches to Qemu v0.11.0 needed to work with GNS3

Older Qemu releases v0.11.0 or v0.14.1 are better suited for running Cisco ASA on GNS3 than newest Qemu versions. However, Qemu releases before version 1.1 must be patched to work with GNS3. Patches can be downloaded from the following site: http://www.gns3.net/qemu/

This repository includes all necessary patches to Qemu v0.11.0 needed to work with GNS3. They include patches from http://www.gns3.net/qemu/, as well as additional new patches:

0001-qemu-0.11.0-fix-build-errors.patch - new patch which fixes build errors (tested on Ubuntu 14.04 64bit)

0002-qemu-0.11.0-olive.patch - combines all patches from http://www.gns3.net/qemu/

0003-qemu-0.11.0-monitor-udp.patch - new patch for new versions of GNS3 (after v1.2.2) needed to control running Qemu VMs
