I can confirm issue with all LAMP server (debian based) since PVE7 upgrade Dont know if its related to kernel or qemu I will move VM to pve 6.4 in order to confirm

Hi, I recently upgraded a 6 nodes PVE cluster to PVE7 cat /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor performance Users report me some issues (lag, freezed browsers for 1 min) for several LAMP VMs... Everything seems to be ok inside the VMs including pve nodes ressources... I'm...

Hi, Does it mean that you recommend to not upgrade 7.0.x before openvswitch availability for pve 7 ?

Thanks a lot guys :)

Hi, Is doing 'Verify Jobs' makes sense on a fully ZFS datastore ? Thanks in advance !

Thanks, Yes PVE nodes are connected to the same stack of 2 switches. for each node : - LACP 2 x 10Gb (VM bridge + Corosync ring1) - LACP 2 x 10Gb (Ceph + Corosync ring0) Yes all VMs use HA (default config).

Hi, I plan to upgrade a switch stack (2 switches) which means a downtime of 5 min (or more) I guess. 6 PVE Ceph nodes are connected to this stack, with nearly 80 KVM VMs in HA. Even with shutting down all VM for 10 min, I think that PVE nodes would reboot, and I don't what could be the...

Hi, I recently noticed that my debian 10 VMs reports high disk usage (80-100%) with atop. Here are some screenshots for the same vm (completely idle) ran by several pve kernels Kernel 5.4.114 Kernel 5.4.106 Kernel 5.4.73 any ideas ? Running some basics 'dd' tests writes inside the vm...

Hi, I'm probably affected by this issue too. I also noticed for idle VMs on debian 10 latest kernel 4.19.117 : atop => DSK | sda | busy 97% with avio > 200 ms Had to use openvswitch because of broadcom cards =>...

Hi, On a relatively updated PVE node, I do some PBS backups. Backups are made with snapshot mode and qemu-guest-agent is installed on all VMs (Qemu Guest Agent is enabled indeed). I noticed yesterday that during the backup, I have lot of iowaits on the VM. Backup started @8:41 and ended...

So my proposal is to add a checkbox :) whether or not you want to apply datacenter rules with security group to all VM/CTs

Yes indeed For example, activate the FW for VM (Input Drop - Output Accept) - Then allow incoming connections for some IP ranges (RDP, SSH, Zabbix monitoring...), and doing it for all VM/CTs This is the reason why I thought datacenter rules with security groups should do the trick

Yes understood - but for example, in order to apply the same rule for 120 VMs, you have to apply it manually for each...

With 120 VM/CTs per cluster it should be nice to not settle VM/CT one by one. For example a checkbox 'Also apply on VM/CTs' for datacenter rules

Hi, Thanks. Could be interesting to have datacenter rules applied on all items (Hosts + CT/VMs) dont you think ?

Hi, Rules for the node hosting the VM :

Hi I have the following rules applied at datacenter level : Everything is working as expected for Hosts nodes But not for a VM (by now only hosts nodes are protected by PVE FW) When one of my zabbix proxies tries to ping the VM, it is rejected as you can see in the logs Why...

Hi, In order to prevent a maximum of "existing bitmap was invalid and has been cleared" with multiples PBS this is what I do : @01:00 Backup to Internal PBS => existing bitmap was invalid and has been cleared @10:00 Backup to Internal PBS => OK (very fast) @15:00 Backup to Internal PBS => OK...

Thank you :)
