#10372 obsolete Virtualbox messes up the host only adapters IPs upon upgrade sergiodlc
Description

Any time I upgrade to the newest VirtualBox version I have to go to Preferences -> Network and edit the details for the host only ethernet adapters to set the proper IP address. It gets reset to 192.168.56.1. The IP that I set before upgrading should remain in place instead of being reset to some predefined value.

#10375 obsolete Bluetooth headset cuts out when starting guest MitchGibbs
Description

I'm running Vbox 4.1.10 on Win7 with a Mint 12 guest. I use a bluetooth headset paired with the host. When I start the guest, almost immediately, the bluetooth headset cuts out. If I disconnect and reconnect the headset, it works again. If I shutdown the guest, it works again.

I thought the guest might be taking over the bluetooth, so I disabled bluetooth in the guest. I'm now fairly sure that couldn't have been it. Everything I've read in the forums indicates that bluetooth devices are passed through as USB. I've now disabled USB in Vbox's settings for the guest - but the behavior continues.

#10377 obsolete x86 debug registers don't work reliably in a guest OS Eugene153
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.
