fix: enlighten lcow uvmboot with dm-verity boot - #2766
Merged
Conversation
lcow uvmboot wasn't enlightened with dm-verity boot when the feature was introduced for C-LCOW. Address the gap by by setting the necessary lcow options: - `HclEnabled` must be set to false on newer OS builds - `BundleDirectory` must be set, so the template copy can happen - add `-no-verity-boot` flag for backward compat with earlier versions of kernel.vmgs which had rootfs baked in. - `DmVerityRootFsVhd` will be set to the default value from vmutils - `DmVerityMode` will be set to `true` Signed-off-by: Maksim An <maksiman@microsoft.com>
