Aalexskysilk replied to the thread Cloned VMs from template receive the same DHCP IP address.Delete the mac address from the NIC before starting it. I believe choosing the unique checkbox when cloning does the same thing.

Ssteve999 replied to the thread Cloned VMs from template receive the same DHCP IP address.I ran into exactly this when building Debian templates for my home lab. What helped me understand it: on Debian-based guests the DHCP client usually identifies itself with the machine ID from /etc/machine-id rather than the MAC address, so every...

Like.
Manuel already noted this is outside what PVE supports. I'd go a step further: I can't recommend doing either of these in production. It's worth being clear about what WSFC actually needs from that disk. It isn't so much the block device as... -
bbgeek17 replied to the thread PX Cluster GUI Storage delay.The most likely culprit is that the NAS response is somehow delayed. Local ZFS should be pretty fast. You could try to temporary disable the NAS storage to see if that returns the GUI response time to normal: pvesm set <storage> --disable... -

I'd make sure you would have good QoS if you don't have dedicated links for Corosync, eveything else seems fine at first glance. Did you plan on running ZFS replication?

JJohannes S reacted to alexskysilk's post in the thread Poor user experience with Windows Server 2025 on Proxmox with Like.
there's your problem. Host exposes the full set of cpu flags to the guest, which means all mitigations applicable to your cpu will apply. in a virtualized environment, mitigations will destroy guest performance- Windows most of all...

MVielen Dank an alle, die mir beratend unter die Arme gegriffen haben. Ich habe mit dem Ventoy Stick die aktuellste Version 9.2.2 installiert und meine Backups wieder zurückgespielt. Und alles läuft. Allein die Tatsache, dass es so etwas wie...

UdoB reacted to Johannes S's post in the thread Best approach for managing Proxmox VPS templates with Cloud-Init? with Like.
Adding to fireons comment I would like to add this: At my place of work I spent the last three weeks creating new vm templates (although we are running vmware but cloud-init isn't that different there). Since I needed to fullfill some special... -

Bbl1mp reacted to SteveITS's post in the thread Any way to isolate VMs on same VLANs/bridge? with Like.
I’ve not tried this here but in my experience with other firewalls, if a connection/state is open adding a drop rule will not close it as the allowed open state still exists. IOW end the ping then enable the rule.

SSpiceGuy replied to the thread [SOLVED] How do I list the directories/file on my local drive?.Hi Ubu, Thanks for the fast reply. What gdu is returning doesn't make sense. This is what it says for the 'local' drive: Copying storage.cfg and opening the copy had this information for the local drive: dir: local path /var/lib/vz...

SInisterPisces reacted to fabian's post in the thread [PDM 1.1.7] Does Live Migration of a Guest between Clusters Require Shared Storage? with Like.
PDM cross-cluster migrations work pretty similar to regular intra-cluster migrations, but there are some differences. intra-cluster: - SSH used as control channel, SSH or plain TCP used for data transfer - live migration of VMs possible, offline... -
Cchughes reacted to ubu's post in the thread [SOLVED] How do I list the directories/file on my local drive? with Like.
cat /etc/pve/storage.cfg gives you the location of your pve storages. (apt install gdu) gdu -x /path/to/storage shows you the usage of the storage (gdu is like ncdu, but much faster)

Cchughes reacted to aaron's post in the thread Memory ballooning doesn't reduce host RAM usage? with Like.
Once the threshold is reached, the host will ask the VMs to return memory to the host. The VMs need to be able to return that memory! That means, a way to communicate with the host via the Ballooning device, and free memory that can be returned...

Cchughes reacted to aaron's post in the thread Cloned VMs from template receive the same DHCP IP address with Like.
Because on Linux, usually the machine ID is used to identify against the DHCP server. Windows usually takes the MAC address. Lookup how you can prepare a Debian based system (which Proxmox VE is) to be a template. You usually need to empty the...

EEdoFede replied to the thread Any way to isolate VMs on same VLANs/bridge?.Sorry for the late reply — old thread, I completely missed the notification. For the record: @Dunuin's suggestion in #2 was the right one, and it does work. My failed test back in 2023 was almost certainly the conntrack issue @SteveITS and @fba...
