Hello,
I'm testing proxmox and a few other alternatives ( xenserver, vmware ), in order to virtualize a few dedicated servers.
I setup a 2 machines cluster and a nfs storage ( in production will use a SAN and iscsi ). I have however a few problems:
3 Of created vms ( all kvm ), have almost all memory being used, one 3gb and other 1gb. Its a plain centos 5.5 install, so shouldnt be with this problem. What can cause this?
Regarding shared storage ( nfs ), i have slow speeds:
[root@localhost ~]# `dd if=/dev/zero of=/tmp/2G bs=1M count=2048; sync`
2048+0 records in
2048+0 records out
2147483648 bytes (2.1 GB) copied, 76.1599 seconds, 28.2 MB/s
Servers ( proxmox and nfs ) are connected to a switch at 1Ge. I should get better speed, no? How can i improve it?
Since i'm migrating from dedicated, i'm afraid that my customers will suffer a service degradation. Shared storage is a must, because of live migration and HA.
Also, another question ( maybe to many in a single thread? ).
Atm in my servers i have three nics ( internet, backend-backups and cdp ). The backend nic ( eth1 ) is used to make r1soft cdp backups. I plan to install this in kvm vms and do a daily snapshot of the VM to my cdp server. I cannot however use the internet nic, as i dont want to have both trafic together. How can i configure the KVM vm to use the second NIC of the server and another IP?
Sorry all this questions and thanks a lot for your time.
