We can limit the amount of bandwidth that can be consumed during the replication process. By default, it is set to unlimited bandwidth. When replicating multiple VMs on the node, it may be very helpful to limit the rate so the running VMs can be used without any issue. The rate limit is defined in MBps.

- Proxmox node issues
- Issue – fresh Proxmox install stuck with /dev to be a fully populated error during node reboot
- Issue – rejoining a node to a Proxmox node with the same old IP address
- Issue – Proxmox installation completed but grub is in an endless loop after reboot
- Issue – LSI MegaRAID 9240-8i/9240-4i causes an error during booting of the Proxmox node
- Issue – the Upgrade button is disabled on the Proxmox GUI, which prevents the node upgrade
- Issue – Proxmox cannot start due to the getpwnam error
- Issue – cannot log in to the GUI as root after reinstalling Proxmox on the same node
- The main cluster issues
- Issue – Proxmox virtual machines are running, but the Proxmox GUI shows that everything is offline
- Issue – kernel panic when disconnecting USB devices, such as a keyboard, mouse, or UPS
- Issue – virtual machines on Proxmox will not shut down if shutdown is initiated from the Proxmox GUI
- Issue – kernel panic with HP NC360T (Intel 82571EB chipset) only in Proxmox VE 3.2
- Issue – the Proxmox cluster is out of quorum and cluster filesystem is in read-only mode
- Issue – VM will not respond to shutdown or restart
- Issue – Proxmox GUI not responding after Firefox update
- Issue – the Proxmox GUI is not showing RRD graphs
- Storage issues
- Issue – deleting a damaged LVM from Proxmox with the error read failed from 0 to 4096
- Issue – Proxmox cannot mount NFS share due to the timing out error
- Issue – how to delete leftover NFS shares in Proxmox or what to do when the NFS stale file handle error occurs?
- Issue – Proxmox issues --mode session exit code 21 errors while trying to access the iSCSI target
- Issue – cannot read an iSCSI target even after it has been deleted from Proxmox storage
- Issue – a Ceph node is removed from the Proxmox cluster, but OSDs still show up in PVE
- Issue – the no such block device error during creation of an OSD through the Proxmox GUI
- Issue – the fstrim command does not trim unused blocks for the Ceph storage
- Issue – the RBD couldn't connect to cluster (500) error when connecting Ceph with Proxmox
- Issue – changing the storage type from IDE to VirtIO after the VM has been set up and the OS has been installed
- Issue – the pveceph configuration not initialized (500) error when you click on the Ceph tab in the Proxmox GUI
- Issue – the CephFS storage disappears after a Proxmox node reboots
- Issue – VM cloning does not parse in the Ceph storage
- Issue – VM disk images stored on ZFS is extremely slow
- Network connectivity issues
- Issue – no connectivity on Realtek RTL8111/8411 rev. 06 network interfaces
- Issue – network performance is slower with the E1000 virtual network interfaces
- Issue – patch port for Open vSwitch in Proxmox not working
- Issue – trying to add a node to a newly created Proxmox cluster when nodes do not form quorum
- Issue – implemented IPv6 but firewall rules do not get applied
- KVM virtual machine issues
- Issue – Windows 7/XP machine converted to Proxmox KVM hangs during boot
- Issue – Windows 7 VM does not reboot, instead it shuts down, requiring a manual boot from Proxmox
- Issue – the qemu-img command does not convert the .vmdk image files created with the .ova template in Proxmox VE 5.0
- Issue – online migration of a virtual machine fails with a failed to sync data error
- Issue – no audio in Windows KVM
- Issue – the VirtIO virtual disk is not available during the Windows Server installation
- LXC container issues
- Backup/restore issues
- Issue – a Proxmox VM is locked after backup crashes unexpectedly
- Issue – how can Proxmox back up only the primary OS virtual disk instead of all the virtual disks for a VM?
- Issue – backup of virtual machines stops prematurely with an operation not permitted error
- Issue – a backup task takes a very long time to complete, or it crashes when multiple nodes are backing up to the same backup storage
- Issue – backup of virtual machines aborts a backup task prematurely
- Issue – backup storage has a lot of .dat files and .tmp folders using the storage space
- VNC/SPICE console issues
- Firewall issues

- Proxmox node issues
