Which value? Do you mean the 0x00020015 and0x00020016? kvm.h shows KVM_TRC_APIC_ACCESS as KVM_TRC_HANDLER + 0x14. I added the PTE_WRITE and PTE_FLOODED after that in kvm.h with the values 0x15 and 0x16. Then in the formats file it shows APIC_ACCESS as 0x00020014, and I added the new PTE entries after that as 20015 and 20016. The kvmtrace_format tool does show those lines in its output which makes me believe these values are ok. What has me puzzled is the 0 values for gpa and gpte. I believe they are not 0 because I added "if (gpa || gpte) before the KVMTRACE_4D(PTE_WRITE, ...) line and the lines still show up in the trace output. david ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
