I am using some VPSes in OpenVZ containers. As I can see, our hosting provider somes moves them between his physical machines. It also means unwaited (and unexpected) reboots.



I have no technical contact with the VPS provider (there is a... complex company structure ;-) ), but I would like to know, what is happening and why.



I checked the /proc/cpuinfo, yes it sometimes changes. But it is not enough.



Can I somehow extract some ID about the host machine, while I have only a root access to the VPS (and zero access to the host)?






proc sysfs openvz

  • As far as I remember openvz: only if the hosting provider has set something up that allows you to.

  • @Henrik Thanks! I've tought on rdtsc to read the cpu cycles since the last poweron from the host cpu; and maybe somehow some cpuid is also available. I think the OpenVZ may have some intentional mechanism to avoid it, but it is not sure.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
