Ale žravost energie tam prý vyřešena není

No to me taky zajímá. Hledal jsem a nenašel jsem ani informaci, že by příčina byla zjištěna, natož odstraněna. Hledal někdo lépe než já?

Ono to nejako vyznamne zerie elektrinu? A v akom pripade - su k tomu nejake dokumenty lebo by som rad vyskusal. Momentalne mam acer aspire one, vlastny build linuxu s kernelom 2.6.38-rc7 tusim jednoducho posledny RC a vydrz je pocitovo dlhsia nez pod win7...

Podrobnejsie info o Xen zalezitostiach, ktore sa objavili vo vanilla 2.6.39

 - Netback (drivers/net/xen-netback). This is a big accomplishment since it
   means that stock v2.6.39 has now a full stack to run guests (the QEMU qdisk
   can serve as blkback backend).
 - PVonHVM can now use PV spinlocks.
 - /dev/gntalloc, which is a driver that can be used from userspace to allocate
   pages to be shared with guests.
 - Xen Watchdog driver (/dev/watchdog) which has the same API as any watchdog driver.
 - 1-1 identity mapping in P2M. Allows us to automatically figure out if
   a page is for an I/O hole or not based on the E820 (means certain drivers work now)
 - IRQ code has been reworked to be dynamic so that we are not limited to running
   155 guests.
 - Making the balloon driver ready for memory hotplug patches and gntalloc.
 - Lots and lots of cleanup patches.

A toto sa nepodarilo pri 2.6.39 dokoncit:

 - Making the TTM layer use the DMA API. This would have allowed us to use the
   radeon/nouveau driver under Xen without trouble.
