Now I'm seeing bunch of warning as: multi.c:3238:d3 guest attempted write to read-only memory page. va page=0xc9000, mfn=0x23491 ... multi.c:3238:d3 guest attempted write to read-only memory page. va page=0xd5000, mfn=0x23491 BIOS map: c0000-c8fff: VGA BIOS c9000-d57ff: Etherboot ROM e9000-e914e: SMBIOS tables f0000-fffff: Main BIOS I guess it's caused by 18931 to update rombios to latest bochs version, and some writes to rom area are added outside of disabling rom write access. But I'm not familiar with this part, and thus hope others (Akio?) may take a deeper dive.
