For this we need to know which bugs are still valid and which co= uld 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 st= ate back to "New" within the next 60 days, otherwise this report will be ma= rked as "Expired". Or mark it as "Fix Released" if the problem has been sol= ved with a newer version of QEMU already. Thank you and sorry for the incon= venience. ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1272252 Title: qemu-img ftp/http convert Status in QEMU: Incomplete Bug description: Converting images with ftp or http as source could be done a lot faster. The way it works now (qemu 1.7.50) is significantly slower than the optimal way. FTP - how it works now 1. Connect and login to ftp-server. Ask for size of file. 2. Get a chunk of data using rest+retr 3. Goto step 1 again in a loop until all data is retrieved FTP - better solution 1. Connect and login to ftp-server. Dont ask for size of file. 2. Retrieve all remaining data 3. Goto step 1 again if disconnected/io error (max NN errors etc) = Http - how it works now 1. Connect to webserver and ask for size of file / http HEAD. 2. Get a chunk of data using http Range. 3. Goto step 1 again in a loop until all data is retrieved. Http - better solution 1. Connect to webserver. 2. Retrieve all remaining data. 3. Goto step 1 again if disconnected/io error (max NN errors). To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1272252/+subscriptions
