I have lots of trouble with Windows 10 KVMs since 5.1 upgrade. Random lookup, bluescreens and reboots with hanging uefi bootscreen. Currently KVM is unsuable. Tried it with kvm64 and host cpu (sandy bridge xeon). Containers running fine. Downgrade is no option because zfs pool is already upgraded.

Updated to 5.1. So far no issues except qm start on kvm's complain about unknown disk format, it uses raw and lock sector 0 or something.

Is your controller battery/flash backed? if not, your controller waits on sync writes until all data is written to disk.

Hi, maybe container content got corrupted?, i get this a lot with Proxmox 5.x. First i thought this is some fiberchannel issue with my cluster. Last week i saw this issue on a standalone system with local lvm storage. Container stopped to start or complain that files got missing/corrupted.

I am the only one with this issue?

Hi, yesterday i upgraded my Proxmox Cluster from 4.4 to 5.0. My Backend is an IBM Storvize Fiberchannel SAN with LVM for shared access. At first everything looks good, containers and VM starting except i had to build SSH Key trust again in my cluster. Trouble starts after creating new...

My upgraded Cluster starts making trouble. LXC Containers failed to start, some start but fails about missing filesystem or ELF headers missing in pam.so and stuff like that. For me this looks like some sort of storage corruption with lxc? Proxmox is running on shared SAN with LVM. I am unable...

I upgraded my 4 Node Cluster today. Live Migration and updating node by node did the job. Thanks for this great Release!

Did you try wget one of the files to see if your machine has proper internet connectivity?

60G Log is way to much. The Log is kept for 5 seconds and then it get flushed to disk. You can monitor this with "zpool iostat -v 1" Avoid using Consumer SSD's. I recommend using Intel Datacenter SSD for your Log.

You have really low fsyncs. Windows use sync writes all over the place and get a big hit if it has to wait for data to be written. Samsung Consumer SSDs are a really bad choice for Virtualization and Servers in general. Here is one of my private (old) Server. ZFS Raid10 4x8TB Seagate Enterprise...

Thank you. I try to update my Cluster tomorrow.

In 4.10 there is essential support for booting Linux on Ryzen CPU's, later versions supports more features and got more optimization.

Hi, i have a small Proxmox Cluster with 3 Nodes and enabled HA for this Cluster. With enabled HA i have trouble updating the nodes, at some point apt restarts the updated Proxmox Services and rebuilds the initrd for the Kernel, at this step Proxmox (watchdog?) restarts the node because it is...

Make a new disk with 750g, transfer the disk/data, remove old disk.I would recommend to do a block copy not avoid touching anything in your customers vm. This involve some downtime.

Hi, i deployed a few CentOS7 LXC Containers today. After taking a look in /etc/hosts i found this.. 127.0.0.1 localhost LXC_NAME # --- BEGIN PVE --- ::1 localhost.localnet localhost 10.48.4.116 xxx.yyy.com xxx # --- END PVE --- The Line 127.0.0.1 contain a placeholder for LXC_NAME instead the...

VirtIO are paravirtual drivers and deliver better perfomance than hardware emulating drivers. Qemu Agents helps communication between Hypervisor and the Virtual Machine for example shutdown event. Balloon Service is explained here: http://www.linux-kvm.org/page/Projects/auto-ballooning

Hi, i use StarWind V2V Converter to convert VMware or Hyper-V Images to Raw. It is a free application for Windows. Then i create a new VM on an filesystem based storage, replace the disk with the converted one and migrate the disk to the final storage (zfs/lvm/...). Hope this helps.

I do it a bit differently, i use just one virtual cd drive and switch the images for installing the drivers. After you are done installing drivers, you load the windows image again and press refresh on the partition list (or you get some error about windows cant be installed...) On driver step...

Depending on your workload, a bunch of enterprises disks with a Intel DC3700S for Slog can give a large boost over some pair of 850s. I had a setup with 4x Samsung EVO 850 1TB in Raid10, burst speed was good, but FSync around 1800 which is really bad. I made another Test Setup with 4x 8 TB...
