For purpose of fast provisioning we need to be able to clone a base LVM, which is raw OS image on it,
Is that possible like what below link said in shared storage environment? ( of course we have SAN storage device)
In latest versions of kernel 5.2+ we can disable mitigations by "mitigation=off" kernel command, but as Proxmox 6 is using kernel 5.0 I've disabled them by using this grub config
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0 pti=off spectre_v2=off nospec_store_bypass_disable mds=off"
For better Ceph performance, I need to disable all kind of kernel protections for CPU vulnerabilities,
Is there any guide on how to ask kernel in Proxmox to do so?
Servers are being used only for Ceph so I have no security concerns regarding disabling CPU vulnerabilities.
I setup OVS switch on 10 nodes which are interconnected via GRE tunnels, but I can see Proxmox is not letting us create more than 4094 vlans because tag ID larger than 4094 is not validated in Proxmox interface or API.
Is there any restriction based on GRE overlay that prevent us having more vlans?
In proxmox documents I can see it's advised to set rstp_designated_path_cost for physical ports, but as I want to create a mesh network with openvswitch containing 20 nodes which all are connected together via GRE is it necessary to set path_cost for GRE too?
I've tried command below but it...
I wonder if there's any exporter that gather guest usage information from inside of them via GuestAgent and export them to prometheus?
If not is it reasonable to use GuestAgent for gathering resource usage of VMs?
I've used a simple iptables rule to test some idea, but I can see it's not picking any packet on tap interface.
Is that normal?
root@node01:~# iptables -I FORWARD -i tap101i0
root@node01:~# iptables -L FORWARD -v -n
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target...
