Make vtpm-stubdom domain compatible to launch on TPM 1.x / TPM 2.0.
Add:
..
extra="tpm2=1"
..
to launch vtpm-stubdom domain on TPM 2.0, ignore it on TPM 1.x. for
example,
vtpm-stubdom domain configuration on TPM 2.0:
kernel="/usr/lib/xen/boot/vtpmmgr-stubdom.gz"
memory=16
disk=["file:/var/scale/vdisk/vmgr,hda,w"]
name="vtpmmgr"
iomem=["fed40,5"]
extra="tpm2=1"
vtpm-stubdom domain configuration on TPM 1.x:
kernel="/usr/lib/xen/boot/vtpmmgr-stubdom.gz"
memory=16
disk=["file:/var/scale/vdisk/vmgr,hda,w"]
name="vtpmmgr"
iomem=["fed40,5"]
