I am attempting to set up the first (of many) Raspberry Pis running Pidora (a Fedora Remix) to boot from an NFS share. It is my goal to eventually place a dozen or more Raspberry Pis in the datacenter I use to power several different services for my infrastructure and clients and hopefully replace some of the smaller VPS nodes that I am currently using. My configuration in cmdline.txt is: dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/nfs nfsroot=<serverip>:/fake/path,nolock ip=dhcp elevator=deadline rootwaitOn the Pi, the output I see is:IP-Config: Got DHCP answer from <router>, my address is <clientip>IP-Config: Complete:device=eth0, hwaddr=<macaddress>, ipaddr=<clientip>, mask=255.255.255.0, gw=<routerip>host=<clientip>, domain=, nis-domain=(none)bootserver=<routerip>, rootserver=<serverip>, rootpath=nameserver0=<routerip>(It pauses for a bit here)VFS: Unable to mount root fs via NFS, trying floppyVFS: Cannot open root device nfs or unknown-block(2,0); error -6Please append a correct root= boot option; here are the available partitions:.....The export configuration is:/fake/path        <clientip>(rw,no_root_squash,insecure,no_subtree_check)On the NFS Server (an OpenVZ Container), the output I see in the /var/log/messages is:Aug 22 23:24:01 vps-4178 rpc.mountd[928]: authenticated mount request from <clientip>:783 for /fake/path (/fake/path)Aug 22 23:24:38 vps-4178 rpc.mountd[928]: authenticated mount request from <clientip>:741 for /fake/path (/fake/path)Aug 22 23:25:25 vps-4178 rpc.mountd[928]: authenticated mount request from <clientip>:752 for /fake/path (/fake/path)Aug 22 23:26:12 vps-4178 rpc.mountd[928]: authenticated mount request from <clientip>:876 for /fake/path (/fake/path)To test, I've made sure I can mount (non-root) from both the Pi and another machine and it worked. Does anyone have an idea on what could be wrong or how to narrow it down? UPDATE:The process has gotten slightly further. The server is still showing the same message, however the client is now saying  is not responding, still trying.Here is the tcpdump (tcdump -vv 'port not 22') during the process:tcpdump: listening on venet0, link-type LINUX_SLL (Linux cooked), capture size 65535 bytes02:27:49.396600 IP (tos 0x0, ttl 50, id 56458, offset 0, flags [DF], proto UDP (17), length 144)    <clienthostname>.3541049940 > <serverhostname>.nfs: 116 read fh Unknown/01000401D2255200F6209D570C172001AA2F2645000000000000000000000000 4096 bytes @ 51609602:27:49.396694 IP (tos 0x0, ttl 64, id 22318, offset 0, flags [+], proto UDP (17), length 1500)    <serverhostname>.nfs > <clienthostname>.3541049940: reply ok 1472 read REG 100755 ids 0/0 sz 1630184 nlink 1 rdev ffffffff fsid 579d20f6 nodeid 120170c a/m/ctime 1408774668.892909 1404929018.000000 1408747025.20258902:27:49.396700 IP (tos 0x0, ttl 64, id 22318, offset 1480, flags [+], proto UDP (17), length 1500)    <serverhostname> > <clienthostname>: udp02:27:49.396701 IP (tos 0x0, ttl 64, id 22318, offset 2960, flags [none], proto UDP (17), length 1264)    <serverhostname> > <clienthostname>: udp02:27:49.396963 IP (tos 0x0, ttl 64, id 34369, offset 0, flags [DF], proto UDP (17), length 72)    <serverhostname>.57067 > <redacted2>.domain: [udp sum ok] 45505+ PTR? <redacted>.in-addr.arpa.
