Re: Write Speeds

2023-07-07 Thread Levin Ng

Hi Groete,


IMO, You should bypass any ACS provisioning to troubleshoot the performance 
case first, which allow you get more idea on the hardware + kvm performance 
with minimal influent, then you can compare the libvirt xml different between 
plain KVM and ACS. That help you sort out the different where it come from, you 
will see QoS bandwidth setting in the VM xml if you do.

We are trying to tell you, when you diagnose the throughput problem, you should 
first identify the bottleneck where it come first.  Iperf is a tools that you 
can test the line speed end to end into your VM, if the result in 1Gbps network 
are near 800+ Mbps, you can focus on the VM performance or the copy protocol 
you are using, try different protocol, ssh/rsync/ftp/nfs, see any different.

You are already test the write-back caching which will improve disk I/O 
performance, it is another story you need to deep dive the pro and cons on the 
write cache, there are risk to corrupt the VM filesystem in some case, this is 
what u need to learn about each cache mode.

VM Guest performance are involved by many factor, you cannot expect VM perform 
nearly the bare metal does. There are long journey to do such optimization, 
take time and improve it gradually. There are lot of kvm tuning guide you can 
reference and prove it on your hardware. Read thoughtfully on each tuning that 
may bring improvement and also introduce risk factor.

Levin

Sorry that I have to ask, can you perhaps be a bit more specific,
please. The only QOS settings I see in service offering are "None",
"Hypervisor" and "Storage", which doesn't really seem network related.
Or am I missing the point? Take note that I use the default offerings
for the VR and VMs but with slight tweaks such as setting local storage
etc and only increased the Network rate from 200 Mbps to 1000 Mbps.

So can you kindly explain by what QOS settings you guys are referring
to, please?

PS, the Write-back disk caching seems to give the VM a slight increase,
I now see writes at 190 Mbps from ~70 Mbps.

Controller type scsi, or virtio performance are similar, no need to worry about

best io performance result, but consume space and lack of snapshot capabliblity

Hi Guys
Does Cloudstack have a disk write speed limit somewhere in its setting? We have been transferring
many files from remote servers to VM machines on our Cloudstack instance and we recently noticed
that the VM write speeds are all limited to about 5-8 MB/s. But the underlying hardware of the KVM
uses SSDs capable of write speeds of 300 - 600 MB/s. My disk offering on my current vms are set to
"No Disk Cache" with thin provisioning, could this be the reason? I understand that

HI Groete,

Should you run a fio test on the VM and the KVM host to get a baseline first. 
SSD are tricky device, when it fill up the cache or nearly full, the 
performance will drop significantly, especially consumer grade SSD. There are 
option to limit IOPs in ACS offering setting, I believe you leave it empty, so 
it is no limit. When you talking about KVM uses SSDs, I think you are using 
Local Disk Pool right? If you have RAID controller underlying, try toggle the

ACS with vmware hypervisors

I was wondering if anyone has any experience with ACS and vmware ESXi as the 
hypervisor?  I'm facing a problem when trying to deploy a new/fresh instance.

I've deployed a vCenter appliance, created a data centre, cluster(s) and the 
hosts have all been added to ACS.  When I attempt to deploy a fresh instance to 
the vmware cluster/hosts to build the OS from an ISO, the following errors are 
displayed/logged:

Write Speeds

2023-07-07 Thread Granwille Strauss


Hi Guys

Does Cloudstack have a disk write speed limit somewhere in its setting? 
We have been transferring many files from remote servers to VM machines 
on our Cloudstack instance and we recently noticed that the VM write 
speeds are all limited to about 5-8 MB/s. But the underlying hardware of 
the KVM uses SSDs capable of write speeds of 300 - 600 MB/s. My disk 
offering on my current vms are set to "No Disk Cache" with thin 
provisioning, could this be the reason? I understand that "Write Back 
Disk Cach" has better write speeds. Also I have VMs set as virtio for 
its disk controller. What could I be missing in this case?

Hi,

Have you configured the switch ports to trunk mode ?
