    Restore VM slowdown Host

    I was thinking it would be SSDs or NFS. But I reinstalled the same server now with Proxmox 3.4. Restoring is perfect no load issues. Didn't want to stay on 3.4 guess have to because of this issue. I feel like I'm missing something but cannot see what that is.

    More interested in the graph. It shows at times it is 100%?

    High CPU load on one server

    Noticed on proxmox server the load has suddenly started going high. We have less VMs on here but they may be pushing more than expected. I assume as its SSD's its not DiskIO that is the bottleneck Wait time as per top can be seen as this: %Cpu(s): 77.3 us, 4.7 sy, 0.0 ni, 17.7 id, 0.0 wa...

    Restore VM slowdown Host

    Now I'm lost. I never had this on proxmox 3.4. Even using cstream is still causing it. So the only similary is SSD being used then. Strange.

    Restore VM slowdown Host

    Is everyone having this issue using LVM? anyone with ZFS having restore issues? I'm starting to think that is the issue. I setup a ZFS server and cant replicate it there. Very weird.

    Best ZFS practices using Proxmox install and after

    In total they use around 36GB on avg. Basicall the KVM VMs are cpanel VMs. We currently use pureSSD disks but trying to save costs with our hosts aswell as have more diskspace on the servers. The Pure SSDs using pveperf is around 500MB/s + So we thought because disks avg usage is 10MB -...

    Best ZFS practices using Proxmox install and after

    New Server we want to setup with the following: 64GB ECC RAM 2 x 240GB SSD disks 4 x 2TB disks for data. New to ZFS and would probably like ZFS caching so we can have it fast as possible. How should the RAIDs be setup for optimal performance? I usually use HW Raid controllers so this is a bit...

    Restore VM slowdown Host

    I ran the following: cstream -t 25000000 | qmrestore /mnt/pve/nfsvzjhb4/dump/vzdump-qemu-102-2017_12_06-19_54_59.vma.lzo 105 Is that 25MB/s I running this but VMs go slow for me as I notice vma extract and lzop running and it takes 300+MB/s Something I'm doing wrong?

    New Server Recommendations

    Good idea will look into that. Also will there be massive impact on performance if we did the following as we host cpanel KVM VPS servers and Plesk KVM VPS servers? 2 x 500GB SSD Disks in RAID 1 (MySQL disks and OS disks) 4 x 1TB Sata Enterprise Disks in RAID 10 (data and /home disks) We used...

    New Server Recommendations

    Hi guys This is our server specs: Intel Xeon E5-2620 64 GB ECC RAM - We usually end up using around 30GB or so per server and the rest is free. H/Ware RAID 6 or 10 (battery backup) 6 x SSD Disks We have always used LVM thin on our servers since Proxmox 4.x but find it slower than when we used...

    Restore VM slowdown Host

    I have the same problem with restores. Only started since we moved from 3.4 to 4.x Now I did notice their is a difference with LVM. LVM-thin is used. Is there maybe something there causing it?

    pfsense with proxmox

    Hi guys, Instead of using Hardware firewalls we are considering pfSense as a VM in proxmox. We have 2 network cards per host node and currently use 1 for public and 1 for backup network traffic and have around 7 nodes we want to use it on. Should we setup pfsense firewall on each node or just...

    LXC Cores vs CPU Limit

    This will be solved eventually. We moved back to SolusVM due to openvz having the loadavg right. Hopefully soon it will be implemented as per the github link. When it does we we will probably move back to proxmox with lxc for our cpanel servers. I just love proxmox. so just Patience :)

    HW Raid controller with BBU advice

    Hey guys We have HW RAID controllers on each server we have. They use BBU with writeback cache enabled. However I'd like to confirm whether on the KVM vms should cache be set to "Default (NoCache)" for best performance? we currently have it set as that. Thoughts and experiences?

    Windows Servers and virtio vs e1000

    We have a host node with 3 VPS servers on it. One of these VPS server for the last few days has been looses network connectivity for no apparent reason and we have not made any changes. It is however a shared hosting server so higher traffic may be occurring. I had a thought now of changing...

    Question: Cpanel and LXC - working better?

    We currently on proxmox 3.4 and want to migrate to 4.x. We used to use proxmox 4.x but had many issues with cpanel vps servers as dont think at the time it was ready. The load of node could be viewed on clients vps servers and they had all the cores of the server node we have 12core nodes.. Now...
