1/ Anchor vNic, the equivalent of linux dummy interfaces, we need more flexibility in the way we setup xen networking. What is sad is that the code is already available in the unreleased crossbow bits... but it won't appear in nevada until Q1 2008 :(
This is a real blocker for me as my ISP just started implementing port security and locks my connection everytime it sees a foreign mac address using one of the IP addresses that were originally assigned to my dom0. On linux, I can setup a dummy interface and create a bridge with it for a domU but on Solaris I need a physical NIC per bridge !$!! @#$! For this particular feature, I am ready to give a few hundred dollars as booty if anyone has a workaround. 2/ Pci passthru, this is really useful so you can let a domU access a PCI card. It comes really handy if you want to virtualize a PBX that is using cheap zaptel FXO cards. Again on linux, xen pci passthru has been available for a while. Last time I mention this on the xen solaris discussion, I received a very dry reply. 3/ Problem with DMA under Xen ... e.g. my areca raid cards works perfect on a 8GB box without xen but because of the way xen allocates memory... I am forced to allocate only 1 or 2 gig for the dom0 or the areca drivers will fail miserably trying to do DMA above the first 4G address space. This very same problem affected xen under linux over a year ago and seems to have been addressed. Several persons on the ZFS discuss list who complain about poor ZFS IO performance are affected by this issue. 4/ Poor exploit mitigation under Solaris. In comparaison, OpenBSD, grsec linux and Windows => XP SP2 have really good exploit mitigation.... It is a shame because solaris offered a non-exec stack before nearly everyone else... but it stopped there... no heap protection, etc... The only thing that is preventing me from switching back to linux (no zfs), freebsd (no xen) or openbsd (no xen and no zfs), right now is ZFS and it is the same reason I switched to Solaris in the first place. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
