Status in QEMU: Confirmed Status in “qemu-kvm” package in Ubuntu: Fix Released Status in “qemu-kvm” source package in Lucid: Fix Released Bug description: Binary package hint: qemu-kvm If kvm is started using two separate "-net user,hostfwd=<forwarding rule>" arguments to forward ports from the host to the client, it won't complain, but will return a connection refused error and hang at 100% cpu when trying to connect to either forwarded port. However, if kvm is started with the hostfwd rules combined together into a single "-net user" argument, it works fine. As an example, this command line doesn't generate any warnings or errors, but causes kvm to hang for me: kvm -net nic -net user,hostfwd=tcp:127.0.0.1:8888-:80 -net user,hostfwd=tcp:127.0.0.1:2222-:22 -m 128 -smp 1 -drive file=disk0.qcow2 ... but this command line works fine: kvm -net nic -net user,hostfwd=tcp:127.0.0.1:8888-:80,hostfwd=tcp:127.0.0.1:2222-:22 -m 128 -smp 1 -drive file=disk0.qcow2 ProblemType: Bug Architecture: amd64 Date: Fri Oct 16 17:19:59 2009 DistroRelease: Ubuntu 9.10 KvmCmdLine: Error: command ['ps', '-C', 'kvm', '-F'] failed with exit code 1: UID PID PPID C SZ RSS PSR STIME TTY TIME CMD MachineType: Sony Corporation VGN-SZ650N NonfreeKernelModules: nvidia Package: kvm (not installed) PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcCmdLine: root=UUID=3ee4953e-48f0-497c-ae78-18cbb18cfef8 ro quiet splash ProcEnviron: LANGUAGE=en_US.UTF-8 PATH=(custom, user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 2.6.31-14.47-generic SourcePackage: qemu-kvm Uname: Linux 2.6.31-14-generic x86_64 dmi.bios.date: 07/12/2007 dmi.bios.vendor: Phoenix Technologies LTD dmi.bios.version: R0081S5 dmi.board.asset.tag: N/A dmi.board.name: VAIO dmi.board.vendor: Sony Corporation dmi.board.version: N/A dmi.chassis.type: 10 dmi.chassis.vendor: Sony Corporation dmi.chassis.version: N/A dmi.modalias: dmi:bvnPhoenixTechnologiesLTD:bvrR0081S5:bd07/12/2007:svnSonyCorporation:pnVGN-SZ650N:pvrJ002VXGP:rvnSonyCorporation:rnVAIO:rvrN/A:cvnSonyCorporation:ct10:cvrN/A: dmi.product.name: VGN-SZ650N dmi.product.version: J002VXGP dmi.sys.vendor: Sony Corporation
