Thanks for these tips! I've not long found your channel and I'm really enjoying your content, well explained and easy to follow. I have quite a few Linux VM's with no GUI for various services and the tip for disabling "Use tablet for pointer" is brilliant. The idle CPU usage of my host has now dropped from 16% to around 5%, just from unticking a box! That's actually quite significant when running 24/7, especially with power being so expensive at the moment.

Great tips. In addition to these, one thing i usually do for all guests no matter the OS, is installing Qemu guest agent. Aso, I would add, that for windows guests virtio windows drivers are mandatory, if you use any virtio devices (you should, the performance increase is noticeable). Most Linux distros support them out of the box. Oh and for multi CPU servers, enabling NUMA is also probably a good idea.

Good tips in here, thanks :) Maybe it's something people do a lot and I just figured out, but I put the IP of each vm/lxc in the notes section (Summery view) as well as any commands I might use often, but not often enough to remember off the top of my head. For example upgrading a specific program a specific way, or backing up a database for a program that has to be done a specific way.

Keeping track of IPs can be a pain for me too. I sometimes use the vmid in the ip, so for exaple 10.1.1.104 would be vm 104. If you have the guest agent installed for a VM it will also fetch the IP of the vm automatically and put it in the summary page for the VM.

I found a nice tip just the other day. By default my Proxmox host was running my cpu at full blast (3.4ghz ryzen 2600) and if you do not want that, it was very simple to change. echo "powersave" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor Has it running at 1.5ghz (iirc) now which is more than good enough for my purposes. I’ve only read into it a little bit but I think there are options for the cpu to boost up/down dynamically as they are designed to. If anyone can point me in the right direction there I would appreciate it :)

You are really a source of dependable information, some of us are not advanced users but need to do something that sometimes require advance knowledge. If I search a topic and find one of your videos, thats really a relief. Thanks for the work and efforts you are putting in. Could you please help about the 2 cases below? First, I just installed a second VM under vertIO 0 block which was already in use by a previous VM. Since the previous VM failed to start, and I had to reinstall it. I just want to be sure if the virtIO blocks 0,1... act as individual system harddrive and multiple VMs can't be installed in one block?? Second, Could you please also tell me what is the way to pass through hdds without any emulation, I am using a QM SCSI pass through with script to OMV VM, but I don't have access to the smart data inside OMV. Thanks in advance.
@ElectronicsWizardry
Жыл бұрын
By block do you man the virto0 and virtio1 names that are used for drives on a vm? Those are specific to a vm and multiple systems can use a virtio0 device. Multiple VMs should share one storage on disk as they will overwrite each others data and cause issues. For the hdd passthrough there isn’t a full passthrough option I know of. I’d rather monitor smart data in proxmox or let proxmox handle the raid and present a virtual disk to the vm. Otherwise you can pass through the disk controller via pcie passthrough but this requires a compatible hardware configuration.
@neail5466

@@ElectronicsWizardry Hi, thanks for the reply. About the virtIO blocks I have learnt that the hard way, in you writing I believe you wanted to say that those can be read from multiple devices and written by one one... Yes I didn't had a idea and neither proxmox warned about that. I thought there would be further segmentation depending on OS installs.. which is wrong. And about pass through I am using my disks by the PCIe RAID controller in IT/JBOD mode..and after many hours of research understood there is probably no way to directly mount the raw drive to the VM, whatever I do it would be an emulated instance. Thanks for having time to responding to my query.

In proxmox resizing the disk for a vm is as easy as adding space in the gui. You need to then configure the vm to use more space. In windows you can use disk management to expand a partition. You can do the same in most Linux distros. You can also use tools like disks to increase the partition size and then expand the partition using the filesystem tools.

@kingneutron1
6 ай бұрын
I was a big vmware workstation user for years, then switched to Virtualbox when they fired the entire desktop devel team. Virtualbox /cannot/ do 10gbit networking speeds in VMs, period. Proxmox can - tested with iperf3 :). I thought I didn't have a use-case for it at first, but it's very powerful. And being based on Debian, I can still use my usual root sysadmin scripts. I bridged 3/4 of my Qotom "firewall appliance" 10-Gbit SFP+ ports together on Proxmox easily with MTU 9000, and briefly had the 4th port separate on MTU 1500 (I got rid of that 10gbit adapter for not supporting 9000 tho.) I have it running 3x VMs to provide DHCP addresses for 2.5Gbit LAN, 10-Gbit LAN and a Host-Only network (pfsense, opnsense and ipfire. Makes it easy to test different distros. IPFire runs in less than 512MB RAM! for my limited needs.) Plus several Win10 VMs, one of which was fresh-installed from ISO and is now running BOINC. Also have a couple of livecd / internet-boot VMs and am learning about LXC containers (and newly-discovered bind mounts.) Also tested P2V Win10 restore with Veeam over Samba using 2.5 and 10-gbit network. Worked fine. Lots of cool things to learn, MIGHT go with a separate 2-node cluster and see about live migration between hosts...

@@Jay2k1 On a 16GB-or-less host, you pretty much have to decrease ZFS RAM use if you plan to run a number of VMs. 1-2GB limit is usually enough for homelab. You can make it up somewhat with an L2ARC cache device; even a partitioned usb3 thumbdrive to share between (small) pools can help there. They have the advantage of being inexpensive - if one dies you can just replace it -- and L2ARC survives a reboot these days. Informal testing ' ls -lR /zpoolname >/dev/null ' and ' find /zpoolname >/dev/null ' with a cheap thumbdrive L2ARC partitioned and shared between 2x single-disk pools resulted in subsequent runs taking much less time than the 1st. Host still had plenty of RAM for VMs
