Using SYSCALL/SYSRET in a 64bit guest OS (running as a VM) causes #UD
By dm_nik4
Hi I have an RTOS 64bit which uses SYSCALL/SYSRET for system calls. They work fine if this OS is executed "native" on an Intel machine. Now if I use a VMM (under development, 64bit) and start the OS as 64bit guest VM the SYSCALL causes an invalid opcode exception. The EFER.SCE bit is set and no LOCK prefix is used. I've also tried to use SYSENTER/SYSEXIT in this OS and they work just fine. I'm not sure if I have setup the VMCS correctly. Are there any hints or special settings in VMCS regarding SYSCALL/SYSRET when running virtualized? Intel machine has an Intel Xeon CPU W3520 with VT-x/VT-d enabled. Any help is appreciated, thx in advance!
Understanding VmExit due to exception
By interruptrequestpacket2
I discovered that the real question is: how can I determines if the exception was caused by VMM or by guest software itself?
bug check 0x7f
By darksider1
Hi! i'm from Russia, and my english is not good. i have some problem with windows 7. After start vmlaunch i have bug check 0x7f(first parametr D). BUT if i put int 3 interrupt in my non-root code(after vmlaunch) then guest OS works good. This bug there only on windows 7. On windows XP driver works good without int 3. In advance say thank
handling Vm exit caused by exceptions
By interruptrequestpacket2
Hi all, I've a question:I've to handle exit for each reason that caused the exit for an exception, and I've to do that in the same way (with an entry injection if it is caused by guest software or with a restore without condition if it is caused by vmm)? Or can I have an example of different handling for different reasons of an exit caused by an exception please (or some kind of explanation)? Thanks in advance, irp
vmcs updating
By steven7652
Might anyone be familiar with the VMCS status updates during VM Exit's. I thought the vmcs would automatically contain updated values for the IDT and or CR3, also the guest SS reg is questionable. Do we have to update these ourselves on each exit for them to be current? If so, which fields are self updating and which are not? Thanks.
Where could I find some examples of Intel VM Extensions (VMX) technology?
By Sergey Kostrov2
I'm currently reviewing a'Chapter 19 - Introductionto Virtual-Machine Extensions' of the Intel 'System Programming Guide' ( Vol 3B ) and my question is: Where could I find some Assembler orC/C++examples that demonstrate how theIntel VM Extensions (VMX) technologyhas to be used? Best regards,Sergey
performance impact of disabling Interrupt Remapping (IR) in VT-d
By Hariprakash Govindarajalu1
Hi, If we keep DMA Remapping and disable Interrupt remapping functionality what is the performance impact to a VM or VMM. Is there any performance data/graphs available. Thanks
