I am new from Xen to Promox questions

[frankyds]

Hi,

I am testing Proxmox with KVM Linux and for now i believe this is a fantastic product.

A few questions:

1. After the default ISO installation, is proxmox secure or do we need to install a firewall on the host?

2. For running Debian Lenny (32 or 64bit), what are the best options creating a vm? Raw image? Qcow2? Virtuo?

3. I am testing now on a new server, the only one that is not in use for production. If i want it in production, and want to use as cluster. Is it ok to install the vm's on this machine as primary node, and add next week the second node? Or need the primariy node have no VM's while installing the second node?

4. Not really a proxomox question: For benchmarking disk I/O's, what is the best application to use?


Thanks

you should use a firewall (extra box). some user posted some firewall scripts on the host, or shorewall, just search this forum.

2. For running Debian Lenny (32 or 64bit), what are the best options creating a vm? Raw image? Qcow2? Virtuo?

virtio for net and block, raw. (qcow2 has some extra features but its also an additional layer which cost some performance).

3. I am testing now on a new server, the only one that is not in use for production. If i want it in production, and want to use as cluster.

you can install VM´s and you can add nodes whenever you want. but the nodes should not have an VM´s - or at least you have to make sure that they do not use the same VMID´s before you join.

on the host, use a simple one: 'pveperf' gives a short overview. benchmarking is quite difficult on VM´s, but there is also a lot of information on the forum > search for it. think of using LVM block devices directly and also SAN.

thanks

you have a typo here?

you can install VM´s and you can add nodes whenever you want. but the nodes should not have an VM´s - or at least you have to make sure that they do not use the same VMID´s before you join.

what do you mean?

 

[frankyds]

you can install VM´s and you can add nodes whenever you want. but the nodes should not have an VM´s - or at least you have to make sure that they do not use the same VMID´s before you join.

did you mean i can have VM's on master and add nodes, but those new nodes should nog have VM's?

 

[tom]

yes. an example:

you create a master and create a new VM (ID will be 101).

now you install a second Proxmox VE host, and create also a VM. as this is machine is not part of the master, it will also start with 101. if you join this now, you have a problem as the cluster has now two 101 which is a conflict. clear now?

 

[frankyds]

yes thanks !

Guys,

I got a server with Red Hat 5.2 with Xen, and i wanna to install Promox VE from scratch..however i wanna to keep the VMs installed on that system...do you know which is the best process to do such thing?
Thanks!
