From: Jan Kiszka <[email protected]> The VMX implementation of enable_irq_window will raise KVM_REQ_IMMEDIATE_EXIT if an interrupt window shall be opened during nested vmrun. We have to transfer this request into the local variable to avoid looping over a continuously re-asserted request on vmentry.
This issue only affects nested VMX scenarios.
