I have one Proxmox VE server that hangs on boot. With "quiet" disabled, it hangs at "Job networking.service/start running (7min 30s / no limit)." If I move /etc/network/interfaces to /etc/network/interfaces.no, the machine will boot up. If I then log in to the machine and rename the file back...

We have been testing Proxmox Backup Server, because it's got a lot of really strong features. In principle, I really like it. In practice, it's causing some pretty serious problems. On VMs with large disks, the backups are positively glacial. Example: INFO: Starting Backup of VM 1914...

While upgrading proxmox to research some problems (discussed elsewhere on here), at one point we had five proxmox clusters going due to various combinations of CPU type and Proxmox version. This makes it really tough to find a particular VM. Even at the best of times we have two production...

Data corruption appears to have occurred while using "Move Disk" on a KVM VM running Ubuntu Xenial that is a database server. The MySQL server crashed during the migration and refused to start, citing InnoDB checksum errors in several tables, many of which had not been written to in months...

We have reinstalled two Proxmox 3.x machines to 4.3 and on both machines, after the install, they come up with this error when booting: Loading, please wait... Volume group "pve" not found Cannot process volume group pve Unable to find LVM volume pve/root Gave up waiting for root device...

Is it theoretically possible to PXE boot a diskless server into Proxmox and then have it use a ceph block device as its root filesystem? The incremental cost of putting at least one SSD in a node, however small, doesn't seem like a lot in terms of cost, power, and failure point, but over a...

vSphere has a feature "Enter Maintenance Mode" where a host can be marked for maintenance, which causes all vm's running on that host to queue up and migrate to other hosts in the cluster in an orderly fashion (i.e. not all at once) so it can be safely rebooted for updates and config changes...

Converting our very oldest Proxmox cluster to 3.1. Grabbed this screenshot before shutting the last machine down: http://imageshack.us/f/692/vdpl.png/

Suppose there is a Proxmox server with 4 network interfaces (eth1 - eth4) in a bonded LACP (bond0) configuration and 9 virtual machines evenly spread across three VLANs (1 - 3). What manner of network configuration will give the best performance and functionality? Currently it is configured in...

While doing some research on the possibility of setting up Xen-style serial consoles for KVM virtual machines on Proxmox, I found that past comments on the subject by Proxmox folks are basically, "There is ssh and there is VNC. There is no use-case for anything else." The big obvious problem...

Hello, I have a few Proxmox 1.9 servers running in a test configuration. I noticed this morning one went to "nosync" and I logged in, the root fs was full because /var/log/syslog took up the entire disk. I rotated it out and hupped syslog. Sync is now fine, but the /var/log/syslog file is...
