@Falk R. made an "install.bat" script which use the devcon.exe Microsoft utility to create the phantom/fake scsi controller. This allow booting directly in PVE with Virtio SCSI disk. Just tried today. Download the virtio win mod drivers ISO , the run "install.bat" , backup/clone to PVE. it's...

Nutanix runs on QEMU. There is no graphic acceleration. iirc, they have already done some work for Intel CPU : https://forum.proxmox.com/threads/high-vm-exit-and-host-cpu-usage-on-idle-with-windows-server-2025.163564/post-842026

as always "it depends" here, for VMs with MSSQL, DBs ~2G, I only rely on Proxmox Backup Server as MSSQL VSS writer ensures consistency. Hookscript not required. For some VMs, DATA and DBs backups are done within guest, only system vdisk is backup by Proxmox others vdisks are excluded. Proxmox...

keep it for Windows guests, as snapshot is done within guest, like Windows Backup or Veeam done the job. Disabling is not recommended, because in-use files like databases can't be consistent, except if you shutdown databases engine and close in-use files.

After a try , ipset created with PVE UI cannot be managed with ipset direcly. ipset created with PVE UI can be updated with CLI pvesh create /cluster/firewall/ipset/my-pve-ipset-name --cidr x.x.x.x/y but too slow if many lines. editing cluster.fw directly is instant.

please try to read what you paste :oops: you see the gateway is not the correct one. then check your DNS from Web UI or CLI /ect/resolv.conf

so your gateway is 192.168.1.254 not 192.168.1.1

Edit : UdoB link is less complicated. I use this script https://github.com/mkorthof/ipset-country on a host customize the code to keep ipdeny.com download/update and ipset generation/update Remove firewall/rules parts Then use the "ipset" generated directly in PVE firewall.

Just hit a bug with Realtek on PVE , 10 MB/s download speed from LAN while 110MB/s download speed from WAN IP (NAT rule on router). Try disable offloading : ethtool -K enp1s0 gso off gro off tso off ( Credits to Gemini for my case because was focus to Windows which run the nginx http server...

WSL requires Hyper-V platform. BTW, I don't understand the point of running Ubuntu VM in Windows VM in Proxmox.

Nice catch. Reproduced here : i440fx doesn't boot with ISO Windows 10 build 1904x.6456 (the EoL build) on a PVE 8.4.16 EPYC 2th Gen host and a PVE 9.1 i5 6th Gen host , vCPU type isn't relevant. EDIT : Only reproduced with the updated iso , with the ISO Windows 10 RTM 20H1 build 19041 boot is OK...

disable Hyper-V feature, so will be back to auto when you enable the Virtual Machine Platform Windows

if device is not mounted, backups are written to / filesystem. umount and delete backups if they exist in the mount point. use chattr +i /mnt/.../proxback to prevent its usage when mount is missing.

Try set "Max perf" power profil in your host BIOS. Do bench to have some numbers comparaison, like Passmark.

Check/adjust your /etc/modprobe.d/zfs.conf then update-initramfs -u -k all

Proxmox VE, with its default vmbr0 Linux bridge, acts like a hardware switch, it does not manage guests network configuration. But you can block ipv6 with PVE Firewall. Enable it in each guest and each guests nic. Then set NDP to "No" in each guest.

if PVE firewall ON , try https://forum.proxmox.com/threads/turning-on-firewall-with-accept-policies-everywhere-makes-hosts-unreachable.182123/post-846186
