Hi Yifan, I believe Linux boot with FEAT_VHE enabled is not supported in gem5 yet.
The VIRTUALIZATION feature is supported, but there were some problem edge cases so it was not enabled by default in gem5-21.2 and earlier. We expect it will be enabled by default in the next stable version of gem5. The `have_vhe` parameter was removed because it was replaced by the `ArmExtension.FEAT_VHE` enum in ArmSystem.py. However FEAT_VHE support remains disabled by default. Best regards, Richard.

I tried running Linux of ARM architecture by GEM5 v21.2.1.1 with feature `FEAT_VHE` and `VIRTUALIZATION` enabled, but it stalled in `paging_init`. The Linux is compiled from https://gem5.googlesource.com/arm/linux, branch `gem5/v4.14`; and the bootloader is `boot.arm64` downloaded from http://dist.gem5.org/dist/v21-2/arm/aarch-system-20210904.tar.bz2. This problem is quite similar to https://gem5.atlassian.net/browse/GEM5-901. I noticed that in GEM v20.1.0.3, a parameter `have_vhe` was added, in commit https://gem5-review.googlesource.com/c/public/gem5/+/39695. This parameter was removed in a later commit https://gem5-review.googlesource.com/c/public/gem5/+/51010. Can GEM5 running Linux using Arm ISA with FEAT_VHE support?
