Can you check if normal grep command works instead of use egrep, and if not, change to use equivalent grep -E? Also, are the quotes needed? Isn't command expansion just enough?

Don't use export nor set explicitly the command to be used, just reassign the QEMU environment variable like it was done before. Have you check if the -enable-kvm flag actually doesn't work on Windows? If so, have you check the -M accel=kvm:tc arguments enable KVM on Linux?

Remove this else branch, or at least the assignation of the QEMU variable.

Using mingw (or even the bash that comes with git-scm), and the windows build of QEMU gets us right up to the point of running NodeOS, but the original
qemu.shscript doesn't detect KVM in a way that allows Windows to launch it, instead complaining about no accelerator detected.The patch borrows from lrvick/airgap#3 to circumvent this error. Working on windows 10 with the
v2.10build of QEMU.
