qemu arm versatile bug hunting

  1. lsi scsi bug patch -> upstream merged
  2. smc network patch -> upstream merged
  3. dhcp server: option interface-mtu 1500; debian arm versatile installer send size > 1500 packet to network, but the host network MTU is 1500. /sbin/ifconfig will indidate the host network MTU -> not real problem?
  4. install apt-cacher(not apt-proxy) to get network more stable.
  5. tun/tap: /etc/network/interfaces : bridge_fd 1
  6. the vnc server in qemu is not so robust. you must disconnect normally. real vnc viewer F8 will pop the menu, and then click "quit viewer"
  7. DNS server is not stable. 140.113.250.135 is nctu primary DNS server and assign ip address for mirror site
  8. RTC not implement, delay will be infinite delay(I guess debian installer hang)
  9. apt-proxy sometimes need restart because the connections are not normal termination or the mirror site synchronization problems. If information show "some package can not got", you need to restart apt-proxy. (you should change to apt-cacher)
I don't know if the fixed is useful.
But I can install arm debian in qemu 30 times automatically without problem.
The version is debian-v2.4. the version is a private version control number not link with upstream.

Wang Cheng Yeh is me.
