[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] Add initial VMX support to xm-test:
# HG changeset patch
# User stekloff@xxxxxxxxxxxxxxxxxxxxxxxxxx
# Node ID 9558361d8040c2a6830dffba73226c7ed2f57a52
# Parent da3b19d7bf9ea1b0bc351e6b9aad083e36cf3746
Add initial VMX support to xm-test:
1) Added script create_disk_image to make full virt image
2) Changed XenDomain.py to build separate XmTestDomain object
for vmx guests (this structure will need to be cleaned up)
3) Changed ramdisk Makefile.am to create disk.img if vmx configured
