“Hi, Proxmox can really do a lot of things”
1. Introduction
Proxmox VE (Proxmox Virtual Environment) has a user-friendly web interface, a JAVA-based UI, and kernel interfaces that allow easy operations for VM clients. It also features convenient template functionalities, making it quite similar to foreign commercial VPS environments. It supports VT and iSCSI, which is practical for managing virtual clusters in small to medium-sized enterprises.
2. Basic Operations on the Host Machine
Before installing Proxmox, ensure that CPU virtualization support is enabled; this can be done in the BIOS, following the motherboard’s manual. Generally, this should not pose any issues. Next, install Proxmox using a USB drive.
/etc/default/grubGRUB_CMDLINE_LINUX_DEFAULT="quietto:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"update-grubTo verify its effectiveness, use the following command:
dmesg | grep -e DMAR -e IOMMU
//Note: If the command dmesg | grep -e DMAR -e IOMMU does not produce output, it indicates a problem. It is likely an issue with the BIOS settings, and you need to enable VT-x support for the CPU. For AMD CPUs, the /etc/default/grub file should be modified to GRUB_CMDLINE_LINUX_DEFAULT=”quiet amd_iommu=on. This option also supports several values that can be added as needed.
3. Adding Modules
Modify the following file:
/etc/modulesAdd the following lines (default is empty):
vfio vfio_iommu_type1 vfio_pci vfio_virqfdFirst, find the network card ID (Note: Remember the ID value preceding the output information).
lspci | grep net
Then, enter the system and open the following file:
/etc/pve/nodes/YourClusterName/qemu-server/VMID.confManually add the following content:
machine:q35 hostpci0:02:00.0,pcie=1 # NIC 1 hostpci1:02:00.1,pcie=1 # NIC 2
//Success will display the corresponding NIC information above.
If you accidentally add a NIC used by the physical host, it will cause the server to disconnect. In this case, use a USB drive to enter rescue mode, delete the original configuration, and restart.
