In this case it came right out and said it has been activated too many times. (we swapped hardware a couple of times before virtualizing).

Well I to stepped into this trap and have painfully discovered that with Windows 2008 R2 Retail there is a limited number of re-activations I can do. I am now facing purchasing a new license! Does anyone have any ideas on how to avoid this in future upgrades and how to resolve this on our...

Hello everyone, I have a Centos 5 Samba server as a PDC at our master site (192.168.0.0/24) and I have a remote site (192.168.1.0/24) connected with a IPSEC VPN (pfsense, boths ends are behind a NAT router). All ports and protocols are open through the pipe. All servers and routers are...

I am running Proxmox 3-2-1. I have a Windows 2008R2 VM running. When I go to add a DVD Drive I get this error "checksum mismatch (file change by user?) (500)" and it fails. It does not make any difference which media I select. This machine will also not restart from windows. I get the BSD. It...

I believe the P400 only supports 1.5 Gbps in SATA mode, 3.0 Gbps in SAS mode.

I thought about leaving off the IP but I already set it up with one and now can't remove it. In any case I installed UFW with this setup: ufw default deny incoming ufw default allow outgoing ufw allow from 10.10.1.1/24 ufw allow 8006/tcp ufw logging off ufw enable ufw enable systemctl enable...

I know this has been asked a thousand times ..... I would like to use Proxmox to test various software firewalls. My plan is to install the software firewalls as VM’s and isolate Proxmox from the internet. I have read many of the forum postings and I am not clear on how to do this. What I...

Hello everyone, I have a HP DG380 with a P400 RAID controller configured with a two disk RAID 1 array. I am not able to install Proxmox 3.0 on it. The installer does partition the disk but I am getting errors “can’t create file. Disk is read only”, etc. I am able to install Centos 5 on the...

Re: Best practice for mutiple guests with public access Multiple guests connected to one physical NIC. For example guest VM's A, B and C would all be accessible from clients on the physical network through eth0.

Hello everyone, It looks like there may be more than one method to have multiple guests have public IP's to the same external network (Multiple guests connected to one physical NIC. Guest VM's A, B and C would all be accessible from clients on the physical network through eth0). Configure...

Re: Challenging networking problem Resolved .... this was a tough one. I confirmed this on a Proxmox host and a Centos host. The hardware NIC is an Intel 82546EB. Promox uses the e1000 driver for it. The Centos guest was configured with a virtio driver. When I switch to the e1000 guest driver...

Re: Challenging networking problem Hi Udo, I have not configured any proxy on the host nore the guest. The gateway quest is not running in proxy mode yet but will have to be later. I was planning on having the proxmox host bypass the proxy in the gateway VM server settings. Thanks, Kevin

Re: Challenging networking problem Hi JimBeam (why am I suddenly thirsty?), your addresss and gateway have an "x" in them. Is that literally how they are or are you masking them for this post? Tonight I will change my network scripts so the fast NIC comes up as eth0 and try this again...

Re: Challenging networking problem Thanks for the quick response Udo. 1. Firewall is not turned on ... yet. And one more piece of info I forgot. Other network clients physcally connected to eth1 work just fine. No issues. So the problem is only with Proxmox itself and the other VM on Proxmox...

Resolved ..... Hardware NIC is Intel 82546EB. Proxmox uses the e1000 driver. Changing the driver from virtio to e1000 in the guest configuration fixed the problem. Hello everyone, I set up a new Proxmox server and installed Router/Gateway/DHCP server (ClearOS) as a VM. My idea is to only...

Thanks Rob

Hi Rob, After reviewing the readme file https://github.com/mpalmer/lvmsync#readme I can't see how this would work for me unless I have a snapshot running all the time (I do not want to take the performance hit on the host). Basically for an nightly incremental backup: Create an initial...

That looks interesting too but it appears that you have to have a snapshot running all the time.

resoli, would you please post what you have so far for your script?

Hello everyone, I have a thought here an want to get some feedback before I test it. Can we perform a differential backup of running Linux VM LVM devices by: Create a snapshot of the LVM device in the Proxmox OS Mount the LVM snapshot in the Proxmox OS Perform a rsync to a mounted LVM on...
