General questions regarding FreeBSD 10: 1. Did virtualization containers (VPS) make it into FreeBSD 10? The documentation I=92ve read implies that you can have nested containers, with little to no performance penalty, is this correct? How is networking handled inside these containers? 2. I'm assuming jails still exist in FreeBSD (I haven=92t used BSD in a lon= g time), how do they relate, or fit in, with VPS and Bhyve offerings? Is Xen Dom0 or KVM available on FreeBSD? 3. Can Bhyve be used with processors that don't support Extended Page Tables? For example, Xeon 5400 series processors? 4. How well does FreeBSD 10 run as a VMware vsphere , KVM, and/or Xen guest= ? 5: For Jails, VPS, and Bhyve, what is the footprint (i.e. memory overhead) for each implementation? 6. How stable is FreeBSD's ZFS implementation, relative to Solaris? What zpool version is in FreeBSD 10? Is LZ4 the default compression mode? 7. Is Clang and the build system setup to automatically target cpu instruction set? i.e. cc -target-cpu corei7-avx? Any performance improvements of targeted binaries? 8. Has ports management gotten any better, specifically upgrading ports? Can applications be self contained, like on the Mac, yet? Any work on rollback with ZFS? 9. I recall device support being a large hurtle for me in the past. How far behind is driver development relative to Linux, for server equipment? Has there been any community interest in porting FreeBSD (world) to Linux (kernel)? 10. How is the Java ecosystem on FreeBSD? Is LLVM specific to applications? I make the assumption that the VM in LLVM is referring to something like a JVM, for code abstraction. I haven=92t used FreeBSD in ages. However, VPS, with ZFS, has me really excited; I don=92t enjoy Solaris, and Enterprise Linux is still stuck in 2009, with kernel 2.6.32. I can=92t find any modern linux distributions tha= t are as reliable as I remember FreeBSD was. It=92s really sad. Thanks!
