#3454 obsolete virtualbox 2.1.4 kills my wifi network connection (wireless g notebook adapter wpc54g) foupfeiffer
Description

winxp host works fine with 2.1.2 and very compatible linksys wifi card but something must go wrong with the 2.1.4 drivers because i cannot get any wifi network working after install. When I start VB no network devices even appear on any guests.

Uninstalled and 2.1.2 back on again everything is fine.

I did not test it for a wired nic.

#2381 fixed virtualbox 2.0.2 is unable to "reboot -f" an opensolaris snv_100 guest jkeil
Description

There's a new "fast reboot" feature in opensolaris build 100: http://www.opensolaris.org/os/community/on/flag-days/pages/2008092201/

Problem: virtualbox 2.0.2 is unable to "reboot -f" an opensolaris snv_100 guest (64-bit and 32-bit). The guest shuts down, but virtualbox 2.0.2 guest hangs while trying to start / reboot into the new kernel.

HW: AMD64 X2 cpu, AMD-V enabled in virtualbox. Host OS: SXCE build 96, bfu'ed to current opensolaris bits (2008-10-2)

The guest hangs in fb_swtch_src.s when the kernel switch page tables are installed.

http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/i86pc/ml/fb_swtch_src.s#209

usr/src/uts/i86pc/ml/fb_swtch_src.s:

   209          /*
   210           * Load top pagetable base address into cr3
   211           */
   212          movl    FI_PAGETABLE_PA(%esp), %eax
   213          movl    %eax, %cr3
   214
   215          movl    %cr0, %eax
   216          orl     $_CONST(CR0_PG | CR0_WP | CR0_AM), %eax
   217          andl    $_BITNOT(CR0_NW | CR0_CD), %eax
   218          movl    %eax, %cr0

Workaround: Boot Solaris guest with "-B disablePAE=true", and strip the PAE feature mask (0x200) from the kernel variable x86_feature.
