The security_model=none also doesn't work and get the same error. mahmood@cluster:qemu-vm$ qemu-system-x86_64 -version QEMU emulator version 1.7.0, Copyright (c) 2003-2008 Fabrice Bellard
I know it is old but I think I installed this version three years ago due to the Rocks-6 version old libraries (which is based on Centos-6). I will try some newer versions to find which version is better. One more question. How can I uninstall the qemu which is built from source? "make uninstall" in the source folder doesn't work. Sorry for taking up your time. Regards, Mahmood
