Hi Dave

I am trying to look into XCP to see if I can make change on the code to improve of some scnerio - but it looks like

not all codes are open  - May I confirm this?

I observed that when a node is down - and if my software tried to do shutdown on VMs - it took 20 minutes
for the api  to return Exception - error CANNOT_CONTACT_HOST

for another call like disable_host - it takes 3 minutes to return error : CANNOT_CONTACT_HOST
after the first error - it looks like the second calls - will faster with error -HOST_OFFLINE

May I ask info of Host down etc... stored on storage or memory of XCP ?

I look at the code and saw object call Db.  --> what is this DB ? - is a local file or pool storage ?

Thank you,
