'nested' parameter for kvm_intel module controls whether you're able to
run nested configurations and it is enabled by default, it doesn't say

Could you please describe your environment? In case it is nested, it will look

The unpack facility provides the means to setup a protected guest. A

Protected guests save the instruction control blocks in the SIDA
instead of QEMU/KVM directly accessing the guest's memory.
Let's introduce new functions to access the SIDA.
Also the new memops are available with KVM_CAP_S390_PROTECTED, so

Ballooning in protected VMs can only be done when the guest shares the
pages it gives to the host. If pages are not shared, the integrity
checks will fail once those pages have been altered and are given back
to the guest.

This patchset implements the vector extension for RISC-V on QEMU.
You can also find the patchset and all *test cases* in
my repo(https://github.com/romanheros/qemu.git branch:vector-upstream-v3).
All the test cases are in the directory qemu/tests/riscv/vector/. They are
