Another way to deal with it is to use KVM agent hooks:
https://github.com/apache/cloudstack/blob/8f6721ed4c4e1b31081a951c62ffbe5331cf16d4/agent/conf/agent.properties#L123
You can implement the logic in Groovy to modify XML during the start to
support extra devices out of CloudStack management.
However, it could be a great option to have Cloudstack as an orchestration
mechanism for Proxmox working on Proxmox tooling without highly obscure and
hard-to-troubleshoot Cloudstack router, savm, cpvm. Just dreaming :)

Hi, the qcow2 volumes may be thin, sparse, full. Maybe the fs is slow, so
while the image does cow allocations, the performance degrades? Try to make
a full qcow2 image by:
qemu-img create -o preallocation=full -f qcow2
And check again.

Hi, I use MariaDB Galera cluster.
But you have to pin all the CS management to the same galera node to make
cloudstack transactioned operations work correctly. HAproxy or shared
common ip solve that.

Local storage gives the simplest design and the most predictable behavior.
The live migration is often overrated while host crashes are pretty rare.
We have servers with 500+ days of operation running Cloudstack. So... it's
just fine, at least with KVM.

Looks like a joke. HDFS is not an FS you WANT or CAN use for VM
filesystems.
Its architecture is completely different from what POSIX-compliant OS wants
to keep QCOW2 images (or even RAW images).
If you want fault-tolerant FS, use Ceph or Gluster or even NFS over DRBD.
NFS is a stateless

Abishek,
NFS over a bunch of drives works just fine but has no means for failover
(out of the box, when self-built). If your benchmark shows enough IO
performance per VM, then NFS is just the way to go.
Keep in mind that NFS can have various backing store technologies like

Glusterfs works fine as a shared mountpoint. No NFS and other stuff

Hi, you cannot have multiple local storages for a single host (however it
would be great if it is supported, but not yet).
There is one real-life workaround basically:
1. you add a single host to a single cluster (e.g. C1)
2. you export storage pools from the host as NFS filesystems with scope

Hi Hean,
I've never tried pNFS, but the problem is the same. If you want failover
and hyper scaling, then use Gluster or Ceph. Why would you use PNFS which
is used by almost nobody?
People use NFS because:
1. it's primitive
2. it's easy to manage
3. it supports migrations
4. if planned well

This just means you installed it in the wrong way. Ebtables and Iptables
must be filled with rules like

You have to deploy HA NFS outside Cloudstack. CS doesn't care about storage
fault tolerance.
Gluster is fine (shared mountpoint), Ceph is fine too, HA Nfs can be
deployed with certain approaches or with proprietary appliances.

Even when no SGs used, the agent still creates iptables/ebtables rules and

Hi,
As for 4.11.2, no way to have multiple local storages configured for a
single host. There is no simple way to overcome it. The only one I see is a
pretty ugly - locally mounted NFS, created as a cluster wide storage when
only a single host added to a single cluster...

Hi,
if you use local fs, use just ext4 over the required disk topology which
gives the desired redundancy.
E.g. JBOD, R0 work well when data safety policy is established and backups
are maintained well.
Otherwise look to R5, R10 or R6.

why you think you should be able to ping from the hypervisor? Normally, you

Konstantin,
in general, this feature is very closely coupled with VM live migration,
which is usually undesired and run under human control, and the
implementation depends a lot of the compaction policy used in cloud...
Actually it can be implemented easily outside the cloudstack.
Personally, I

AFAIK, the last CS compatible with container service is 4.6 or smth like
that.

Hi Fariborz, there are no prophets here, we are just humans. Find relevant
logs and post here for a review.

Avoid HV caching when possible, better to add RAM to VM or manage in-VM
writeback settings. Going with HV writeback you end up with angry users
someday, who lost much more data than you can imagine even if you don't use
migrations at all.
Want faster operations - improve your storage, build R0
No, you don't. Only vlan support may be required, but depends on chosen
model.
Ignacio, basic is planned for the removal because 'advanced shared with sg'
does the same. So it is just duplicated functionality. That is why it will
be removed. If you are not in prod, use the option above to ensure better
future compatibility.

Actually, it works like everyone expects. In case of KVM you can just take
a look at running instance with ps xa. But, I don't recommend setting CPU
cap, though... VM will experience CPU steal, and users will not be happy.
Better to deploy nodes with low cpu frequency and many cores.
