Haha , cool. This was exactly the problem - I wanted to send mass trim to all my guests and "trim -av" failed. I just used "df" example since it's more reproducible. Thanks.

I'm new to debian package building, but is there "srpm" style packages available for debian, so that packages can simply be rebuilt without re-making all definitions needed for the debian package system?

I have kinda similar kind of problem. I did get this to work now if I see the referenced "separate all arguments" approach. But I still have problem with dash. This works: root@phoenix:~# qm guest exec 1015 "df" { "exitcode" : 0, "exited" : 1, "out-data" : "Filesystem 1K-blocks...

The command is blocking. It means it will not return before it's complete. If you have a lot of ram (100+GB etc.) then you can actually see it decreasing from proxmox webui under status. Depending on the machine the flushing can occur on ranges of 5-30GB/s.

Don't be so agressive. Did you also follow user micro advice? My edit was only complementary to his solution. And there is storage removal in proxmox UI

Happened to me too once again. pvestatd should really be multithread service so that it would not bog itself down if one of the metrics are not responding. For me I saw that VGS command hung for some reason.

Yes I tested that out also. Got an extra file in my zfs pool. Also it seems it wil dump only needed memory and size of the "hibernate" file depends on the current ram usage. So for faster standby/resume echo 3 >/proc/sys/vm/drop_caches is one way to go. I use it also to make migrations faster...

For me the confusing part is that where is the hibernation data kept? We got some guest machines with 250GB+ ram, so where will this all pushed?

Well... if you make (local) zfs storage with same name on both cluster nodes it will make zfs transfer from one node to another and you still have live migration. This works with local storages (or shared storage which gives separate luns for each cluster node). But this does not unfortunately...

Nvidia is blocking yes. But for me it seemed that every time somebody made a new trick, nvidia detected it. So you could use older card with older driver version (before patch) or cannot get it to work . Did not get this to work with latest drivers at the time (~1.5 years ago). What driver...

Thanks Helmo. Just stumbled on this also and could not figure it out. Removing kernels with your command was good fix. I always remove stock kernels after original install, but this original install was not done by me, so I haven't bumped on this before.

*This worked.* But did not mess around with editing sqlite file. I just removed the whole sqlite db. rm -rf /var/lib/pve-cluster/* It gets recreated after reboot. Proxmox v6.0-9

Is this still broken in v6 version of proxmox?

https://www.altaro.com/hyper-v-backup/webinars/demystifying-windows-server-2016-licensing.php It seems that HT is not a core in terms of microsoft. So you don't have to license HT cores.

Can't we just turn off node B vm's. Copy each machine config file to safe place. Add the Node B to cluster. Add Node B storage (since it will be wiped). Copy back machine config files. All working, without backup/restore? This is assuming, that vm id's won't overlap Would seem like pretty...

Well. I can't seem to pinpoint the problem. Running proxmox 5-1.46 I do have virtio scsi as controller. Fresh installation of centos 7 My config: bootdisk: scsi0 cores: 6 ide2: local:iso/CentOS-7-x86_64-Minimal-1708.iso,media=cdrom,size=792M keyboard: sv lock: backup memory: 10000 name...

I have realtek and have the network disconnect problem. 04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06) I have added two usb ethernet devices to the same bridge and quest works fine with those. Host itself does...

Right you are. I actually investigated this approach, but seems like was too lazy - I misread that there is "," instead of ";". So all good now. Thanks.

Confirmed: if configure it hostpci0: 01:00 then it will just take first pci id and use that one. -device vfio-pci,host=01:00.0,id=hostpci0,bus=pci.0,addr=10.0 Instead it needs to be: -device vfio-pci,host=01:00.0,id=hostpci0,bus=pci.0,addr=10.0,multifunction=on \ -device...

It seems that while 4.2 came with a blast of fresh air, it has broken my box. I have Qlogic dual port fiber cards. I'm using IOMMU to give these cards to my guest system. After upgrade from 4.1 it has only on card available to guest. lspci: 01:00.0 Fibre Channel: QLogic Corp. ISP2432-based...
