| #10377 | obsolete | x86 debug registers don't work reliably in a guest OS | ||
| Description |
Some of x86 debug register events appears lost and not delivered to a guest OS. To reproduce: Use gdb on a Linux guest to run a simple program like this: #include <stdio.h>
int main(int argc, char ** argv) {
char ch = 0;
for (;;) {
ch = ch + 1;
printf("%d\n", ch);
}
return 0;
}
set a hardware breakpoint: (gdb) watch ch Hardware watchpoint 2: ch (gdb) do cont until the breakpoint fails to trigger, e.g.: (gdb) cont
Continuing.
111
112
Hardware watchpoint 2: ch
Old value = 111 'o'
New value = 113 'q'
main (argc=1, argv=0x7fffffffe638) at t.c:8
8 printf("%d\n", ch);
(gdb)
in this case writing 112 to ch did not trigger the breakpoint. The problem appears reproducible with any host, guest or debugger. |

| #6004 | worksforme | x64 Guest will not run on Windows 7 x64 -> HP BIOS bug | ||
| Description |
I am running Windows 7 Enterprise x64 (Fresh install, no other virtualization products installed) on a Core2quad Q6600, 8 GB RAM VirtualBox will not detect VT-x extensions, although they are enabled (I dual boot the system with Windows Hyper-V Server 2008 R2 without any problems running 64-bit guests) VirtualBox reports "VirtualBox - Error | VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of your host computer." |
