2013-07-03 06:55:48 -0600 asked a question the flavor type can keep the same while create instance

Hi all:

I meet something strange, while lanch a instance, I choose the "small" as my flavor type, and I have deleted all the others

after it ,it seems right, like this:

fasd 50.50.10.11 small | 1GB RAM | 1 VCPU | 10GB Disk - Active None Running Create Snapshot

but when i view the detail imformation of the instance, i got the following, the flavor type is m1.tiny:

Instance Overview Info 名称 fasd ID b5853efd-a4e5-4619-94f0-68639cd2ba3e 状态 Active Specs

*类型 m1.tiny RAM 512MB VCPUs 1 VCPU Disk 0GB*

IP Addresses Cloudfoundry 50.50.10.11 安全组 default 允许 -1:-1 来自 0.0.0.0/0 允许 22:22 来自 0.0.0.0/0 允许 1:65534 来自 0.0.0.0/0 Meta Key Name None 镜像名称 cirros Volumes Attached 卷 No volumes attached.

this is very strange, why could this happen? how can i solve this ?

thanks in advanced

2013-06-09 08:12:27 -0600 asked a question vm can not ping outer world with domain name

hi guys: I am new to openstack , I deploy openstack folsom on three nodes as following:

http://docs.openstack.org/folsom/basi...

I success create a instance, everything works well, in this vm ,I can ping others via ip, but when I use a domain name ,i got the following: ubuntu@inception:~$ ping www.google.com ping: unknown host www.google.com

of course, it is the dns problem, but I can't change the file /etc/resolv.conf in vm,cause it always change to the default one, the /etc/resolv.conf in the vm is like this: nameserver 50.50.10.2 domain openstacklocal search openstacklocal

in the vm ,i can ping 50.50.10.2, but in controller i can not ping to 50.50.10.2

I have the dnsmasq run on netwrok node:

network@network:~$ ps auxf | grep dns network 32695 0.0 0.0 8104 928 pts/0 S+ 15:26 0:00 _ grep --color=auto dns nobody 15651 0.0 0.0 27540 1100 ?

In both controller and network , I also add the nameserver 8.8.8.8 into the file : /etc/resolv.conf

here is my question: how could i solve this question and why this situation happens?

Thanks in advance
