Re: [Xen-API] Xenstore data not getting updated in running VM

[Dave Scott <Dave.Scott@xxxxxxxxxxxxx>]

Hi,

At the moment "add_to_xenstore" data isn't 'live': a reboot (or migrate) is required to refresh it.

What kind of data are you using xenstore for? It tends to be good for rarely-changing configuration data but bad for anything which updates frequently. It's also a bit 'fire and forget' while people often want something like an RPC interface.

Cheers,

What 'correct data' you mean? If you write data/foo "bar" from domU you can read them from dom0 as /local/domain/$domid/data/foo

I'm using API VM.add_to_xenstore_data  to add data to a running domU which is reflected in
xe vm-param-get param-name=xenstore-data uuid=UUID_OF_VM but if I do "xenstore-ls data" in domU then it does not reflect the updated/new entries.

If I reboot the domU then it is able to show updated entries with same "xenstore-ls data" command.

Hello List,

I'm not able to fetch correct xenstore data in guest. If I reboot the guest then it loads with latest xenstore data but if I change the content of xenstore data while the VM is running then the data does not reflect in guest.

Is this normal or am I missing anything ?


Note: XCP version 1 and guest tools are installed.
