Thank you all for your thoughtful response.
Rohit, I did try Option 2 with limited success. The architecture I was
targeting was `s390x` and it did give me some ideas on how it can work.
Creating a systemvm template for this arch was tricky as Debian 12 s390x
image and cloud init scripts had
Hi Gary,
Thanks for the sharing
I recall a similar issue caused by a multicast configuration (not the
same):

anyone facing the similar issue could check the multicast configurations.
Kind regards,

host. If

@sbrueseke , I beg to differ, when storage can not be reached all VMs will be
running on read-only disks from there on in. This means the hosts is useless
and VMs need to

@weizhouapache I would suggest to take another look into that and change it
default. In my opinion a host should not automatically reboot at all if no
settings are configured.

@DaanHoogland now I am confused! Why is KVMHAMonitor rebooting hosts when the
host is unable to write a heartbeat file to any storage when any HA setting is
disabled in the UI?

Hey @sbrueseke , I finally got a chance to look at this again.If you are using
NFS this is how it is supposed to work , I think. If you are using LinStor, see

What ways do you guys monitor your Cloudstack servers? SNMP, API, etc?..
