1. For cloudstack 2.2.14, it can't support the ubuntu very well
when adding the ubuntu iso, don't select the relative OS type, select "other linux 64bit", or when creating
VM with this iso, cloudstack will give the following error log:
=================================================
errorInfo: [INVALID_SOURCE, Unable to access a required file in the specified repository:
file:///tmp/cdrom-repo-bw4kHx/install.amd/xen/vmlinuz., ]
=================================================
2. If you can't create the vm successfully, at first, please make sure your xenserver license has not expired.
3. If you want to use vlan function, please make sure your NIC support vlan, or your NIC's driver are latest enough support
vlan function.
For example, when the vm and the v-router on the same host, vm can get ip by dhcpclient from v-router, while when they
are different hosts, vm can't get the ip address, at this time, you should consider whether or not your host's NIC support
vlan function.
4. For basic network mode. we should using security group. when you want to ping vm each other,you should adding the icmp rules.
ingress: icmp type icmp code

5. If you want to reinstall the cloudstack on the same storage, host, etc. make sure you have already made your physical environment cleaned. (storage, DB)
6. SSVM how to download the ISO & template?
SSVM will mount the secondary storage volume to it's local directory, then SSVM will access the http server and get the ISO to it's mounted directory.
So, at first you should make sure the SSVM can ping the secondary storage. then, you should make up a http server so long as it can be accessed by SSVM will be ok
no matter what network the http server located.
