Proxmox falls when is in production

Hi friends,

I have a big problem.

My configuration is a Cluster with 2 nodes Proxmox 3. (Dell 1950 2CPU and 16GB RAM).

This a partition table in both servers:

root@proxmox2:/var/log# df -h
Filesystem Size Used Avail Use% Mounted on
udev 10M 0 10M 0% /dev
tmpfs 1.6G 336K 1.6G 1% /run
/dev/mapper/pve-root 95G 2.5G 88G 3% /
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 3.2G 41M 3.1G 2% /run/shm
/dev/mapper/pve-data 791G 46G 746G 6% /var/lib/vz
/dev/sda1 495M 34M 436M 8% /boot
/dev/fuse 30M 24K 30M 1% /etc/pve
172.16.0.2:/var/lib/vz/storage-proxmox2 791G 46G 746G 6% /mnt/pve/storage-proxmox2
172.16.0.1:/var/lib/vz/storage-proxmox1 791G 156G 636G 20% /mnt/pve/storage-proxmox1

Connected directly with a Gb nic.


I installed the OS in servers in my office with a local ips.
I have been tested with multiple cloning, migration, etc, the CPU load up to 3 or 4, and the VM are not aware. All perfect!! Proxmox is incredible, not fails!


After, I install the servers in the IDC, and I change the IPS of nodes here:

nano /etc/network/interfaces //Edit vmbr0
nano /etc/hosts
nano /etc/issue


I installed a VM-100 (The VM is running the SMTP service on it and Apache Service) and create a Template, all work correctly.

The next day, I Clone Template to other node (Full Clone), the CPU load up to 9, 10, 11, 12.... and VM-100 down. This node not works in Firefox. I forced restart Node and everything returns to normal.

The next day do the same test with a Template, and fails again...


Today, the VM-101 is work in the node, but DNS's pointing to other server, (no customer are using this VM, just is running for testing purposes).
Now, I test the cloning with a Template again, works correctly.... the CPU load up to 2 or 3, clonation is ready in 3 minutes.


Any explanation?


Thanks!! ;)
