Subject: KVM x86: Infinite loop on updating accessed bit in r/o page table
Date: Mon, 24 Feb 2014 19:29:38 +0100	[thread overview]
Message-ID: <530B8F92.50202@siemens.com> (raw)

Hi,

I noticed that KVM (with VMX at least) enters an inifite loop of
vmentries and ept-violations when it has to set the accessed bit in a
guest page table that is in read-only memory (namely: the F-segment of
the BIOS). I don't think this is the proper reaction...
