Hi, This patch series adds virtual suspend time injection support to KVM. (It is an updated version of the following series.) https://lore.kernel.org/kvm/20210426090644.2218834-1-hikalium@xxxxxxxxxxxx/ Changes to v1: - Using IRQ instead of polling to detect the host's suspension. - Removed unused arg "updated" from kvm_write_suspend_time() - Improved comments and commit messages. Please take a look again.
