Sateesh Chodapuneedi updated CLOUDSTACK-9698:
---------------------------------------------
Description:
Currently ACS waits for 15 seconds (*hard coded*) for hot-plugged NIC in VR to
get detected by guest OS. The time taken to detect hot plugged NIC in guest OS
depends on type of NIC adapter like (E1000, VMXNET3, E1000e etc.) and guest OS
itself. In uncommon scenarios the NIC detection may take longer time than 15
seconds, in such cases NIC hotplug would be treated as failure which results in
VPC tier configuration failure. Making the wait timeout for NIC adapter hotplug
as configurable will be helpful for admins in such scenarios.
Also in future if VMware introduces new NIC adapter types which may take time
to get detected by guest OS, it is good to have flexibility of configuring the
wait timeout.
was:Making the wait time for NIC adapter hotplug as configurable will be
helpful for admins so that ACS does not wait for for NIC adapter to be detected
by guest OS, which ensures more flexibility to customers. In future if VMware
introduces new NIC adapter types which may take time (like VMXNET3 in this
case, which takes few more seconds than other NIC adapter types like E1000) to
get detected by guest OS, this fix will ensure flexibility of configuring the
wait time.
