  1. Proxmox 4.0: "no harddisks found" during installation
  2. Building Unified Communications Servers with Proxmox 4

    Nerd Vittles is pleased to announce the release of our new Unified Communications Server tutorial for Proxmox 4. Comments/suggestions are always welcomed.
  3. Proxmox 4 Won't Boot Automatically

    1. True as long as the GPT drive on a non-UEFI platform also has a master boot record. Non-UEFI platforms know nothing about a GUID Partition Table (GPT) so a GPT-only drive would not boot without UEFI. 2. True up to "so..." The drive format matters because the GPT disk label tells a...
  4. Proxmox 4 Won't Boot Automatically

    Let's try this from a different angle. You said Proxmox always labels a drive as GPT whether it is or not. As you observed, this doesn't cause a problem with a legacy machine such as your HP DL160 which is non-UEFI. The reason is because that machine only knows how to boot using the MBR so it...
  5. Proxmox 4 Won't Boot Automatically

    The problem is Proxmox not honoring the Legacy Boot setting in the BIOS. You should never have a GPT-partitioned disk on a non-UEFI or UEFI-disabled machine, and Proxmox should honor that just as all the other operating systems do. Having spent two days on this, it doesn't matter to me...
  6. Proxmox 4 Won't Boot Automatically

    Let's just agree that somebody is wrong. Having a GPT partition can (and often does) cause problems on a non-UEFI machine or on a machine on which UEFI is disabled. See and
  7. Proxmox 4 Won't Boot Automatically

    No, GPT is set by Proxmox during the install based upon the fact that your motherboard has (not uses) UEFI to control the drive. Whether the drive itself can function as a UEFI device without further tweaking in the BIOS is what makes the drive UEFI-compatible. Some can and many cannot. So it...

  9. Proxmox 4 Won't Boot Automatically

    The issue is whether you have a UEFI-compatible drive. If so, it obviously will work fine. If not, it won't... even with UEFI disabled in the BIOS.
  10. Proxmox 4 Won't Boot Automatically

    Not sure how to say it any more clearly. It's a bug because the Proxmox installer does not honor the BIOS setting that has disabled UEFI on the machine. Proxmox creates a GPT disk label type that only can be used on a UEFI-enabled machine. Thus, it will not boot from power on. And, no, "all...
  11. Proxmox 4 Won't Boot Automatically

    That was my first thought as well. But the problem is that this only happens with the Proxmox installer. CentOS 6.7 and Ubuntu 14.04 install fine, and system boots properly. To repeat, the Proxmox installer is NOT honoring the BIOS settings for UEFI and Legacy boot. If UEFI is set OFF and Legacy...
  12. Proxmox 4 Won't Boot Automatically

    The problem with the design (as documented above) is that you end up with servers that won't boot automatically and a cryptic message that "no boot device was found." Since we're talking about Intel motherboards with Intel BIOS, this isn't a rare occurrence and will become more prevalent as more...
  13. Proxmox 4 Won't Boot Automatically

    So... to document the BUG... Proxmox 4.0 and 3.x incorrectly determine that servers are UEFI devices even when UEFI is turned off and legacy mode (only) is enabled in the BIOS. Whether this is due to incorrect information being passed from Intel's BIOS or whether it is a misinterpretation of...
  14. Proxmox 4 Won't Boot Automatically

    For those that are interested, here's the partition layout when the Proxmox installer finishes: This causes all sorts of problems for backup software such as Clonezilla because it doesn't expect to find a bios_grub partition on a GPT-partitioned server. So... it skips /dev/sda1 during backup...
  15. Proxmox 4 Won't Boot Automatically

    Sorry that my link did not meet your standards of political correctness. Wasn't aware that LMGTFY should only be used to insult people. But since you're apparently the resident expert on insults, I'll take your word for it. As for the real issue, here's the solution: When you reboot the...
  16. Proxmox 4 Won't Boot Automatically

    When we troubleshoot issues for folks, we basically want enough information to reproduce the problem so that we can draw our own conclusions and decide whether there is a problem and whether it should be addressed. That information was provided in my first two posts. CentOS, Ubuntu, and Windows...
  17. Proxmox 4 Won't Boot Automatically

    Thanks for your advice. I think you're reading an awful lot into a Google search link. We've been fans and supporters of Proxmox since the very early days. When things come unglued, we typically start with a Google search. When "Proxmox won't boot" yields over 20,000 search results, that's...
  18. Proxmox 4 Won't Boot Automatically

    This doesn't appear to be a hardware configuration issue. Three other operating systems boot just fine. And it would appear to be a historical black eye with many previous Proxmox releases.
  19. Proxmox 4 Won't Boot Automatically

    Proxmox 4 running on Intel NUC D54250WYK1 with Crucial CT250MX200SSD3 drive. When you try to boot, it says “no boot device found.” However, you can manually choose the drive with F10, and it boots fine. Any ideas?
  20. 4.0 Unable to get PID: CT won't start

    Here are the problems from the log. This was after loading nothing but RPMs from the CentOS repo:
