i have 2 nic attached to my VM(centos 7) 1st is NAT, and 2nd is Host only adapter.
the hostonly adapter has become the default gateway, and is restricting my internet access, i want to make my NAT (1st enp0s3) to become the default gateway.
i have tried this, but still upon reboot the host only becomes the default gateway.



# route del default gw 192.168.43.1
# route add default gw 10.0.2.2 metric 100
# route add default gw 192.168.43.1 metric 101


current scenario.

          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...
