[Bug 1687214] Re: Rapid tremendous memory hog when using -net nic, vlan=0 -net user, vlan=0

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to another 
system. For this we need to know which bugs are still valid and which could be 
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state 
back to "New" within the next 60 days, otherwise this report will be marked as 
"Expired". Thank you and sorry for the inconvenience.

** Changed in: qemu
       Status: New => Incomplete
