Re: [PVE-User] Verison 4.x problem with changing IP in /etc/hosts
Hi, Yes you have to change it manual this is intended and not a bug. If you have a cluster you need to change the cororsync.conf too.

I suppose yes since very old kernel has problems with oldest virtio drivers Em 26 de fev de 2017 06:50, "Ml Ml"escreveu: > Hello List, > > i am running Proxmox version 4.4 on a 3 Node Full-Meshed Cluster with Ceph. > > Everythink works greate, except of the IO Performance on VMs which are > Debian 5. > In this Debian 5 VM i run a 2.6.32-bpo.5-amd64 Kernel with virtio and > default cache > > I only get about a write speed of about 35MB/sec. > > With Debian 8 and 3.16.0-4-amd64 Kernel i get about 130MB/sec (which > is the physical limit). > (also using virtio - default cache) > > Is this performance drop with that older Kernel/Dist normal? > > If i have a look at dstat whilest doing my IO Test (on Debian 8 and > Kernel 3.12) i can see much more performance going on the network > interfaces and disk. > > Therefore a hardware bottle neck can not be the reason for the bad > performance on Debian 5 and Kernel 2.6.32. > > Any ideas (other than Updating from Debian5 to Debian8)? > > Thanks, > Mario > ___ > pve-user mailing list > pve-user@pve.proxmox.com > http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user > ___ pve-user mailing list pve-user@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
[PVE-User] Bad IO Performance in "old" Debian Linux VMs
Hello List, i am running Proxmox version 4.4 on a 3 Node Full-Meshed Cluster with Ceph. Everythink works greate, except of the IO Performance on VMs which are Debian 5. In this Debian 5 VM i run a 2.6.32-bpo.5-amd64 Kernel with virtio and default cache I only get about a write speed of about 35MB/sec. With Debian 8 and 3.16.0-4-amd64 Kernel i get about 130MB/sec (which is the physical limit). (also using virtio - default cache) Is this performance drop with that older Kernel/Dist normal? If i have a look at dstat whilest doing my IO Test (on Debian 8 and Kernel 3.12) i can see much more performance going on the network interfaces and disk. Therefore a hardware bottle neck can not be the reason for the bad performance on Debian 5 and Kernel 2.6.32. Any ideas (other than Updating from Debian5 to Debian8)?
