What am I missing here? I tried multiple times with the latest Xvisor on different machines but still can't reproduce the issue you are seeing. We generally provide pre-built binaries with every Xvisor release so I will share with you pre-built binaries of the upcoming Xvisor-0.3.2 release. Maybe that would help you ?

I have dropped this and the patches after this. I'm building the latest Xvisor release with: export CROSS_COMPILE=riscv64-linux-gnu- ARCH=riscv make generic-64b-defconfig make and running it as above, yet nothing. What am I missing here?

I tried the latest Xvisor-next (https://github.com/avpatel/xvisor-next) with your QEMU riscv-to-apply.next branch and it works fine (both with and without Sstc). Here's the QEMU command which I use: qemu-system-riscv64 -M virt -m 512M -nographic \ -bios opensbi/build/platform/generic/firmware/fw_jump.bin \ -kernel ../xvisor-next/build/vmm.bin \ -initrd rbd_v64.img \ -append "vmm.bootcmd=\"vfs mount initrd /;vfs run /boot.xscript;vfs cat /system/banner.txt\"" \ -smp 4 Also, I will be releasing Xvisor-0.3.2 by the end of Dec 2022 so I suggest using this upcoming release in your test.

[PATCH v2 2/5] target/riscv: Update VS timer whenever htimedelta changes
The htimedelta[h] CSR has impact on the VS timer comparison so we should call riscv_timer_write_timecmp() whenever htimedelta changes.
