[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Vitaly Kuznetsov <vkuznets@xxxxxxxxxx>

[ Upstream commit 57a2e13ebdda8b65602b44ec8b80e385603eb84c ]

It doesn't make sense to return the recommended maximum number of
vCPUs which exceeds the maximum possible number of vCPUs.
