[libvirt-users] Cannot recv data: Connection reset by peer
Hello, I'm trying to install and use libvirt 1.0.4 on an Ubuntu 12.04.2. I compiled libvirt by doing: $ ./configure --with-selinux=no --with-gnutls $ make $ sudo make install Everything works fine and are installed under /usr/local Then I started the libvirtd manually and try to start a linux container that has the following configuration: $ virsh -c lxc:/// dumpxml lxcvm1 <domain type='lxc'> <name>lxcvm1</name> <uuid>168edaae-e3b5-2d06-7c65-9aa444a6f234</uuid> <memory unit='KiB'>2097152</memory> <currentMemory unit='KiB'>2097152</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type arch='x86_64'>exe</type> <init>/bin/sh</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/local/libexec/libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/home/thouveng/lxc_dir/lxcvm1/rootfs'/> <target dir='/'/> </filesystem> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain> When I start the container I have the following error: $ virsh -c lxc:/// start lxcvm1 error: Failed to start domain lxcvm1 error: internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_UUID=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_NAME=lxcvm1 /bin/sh error receiving signal from container: Input/output error The libvirtd is started with info option so I can see: 2013-04-03 08:49:20.167+0000: 17046: error : virNetSocketReadWire:1362 : Cannot recv data: Connection reset by peer 2013-04-03 08:49:20.267+0000: 17051: error : virLXCProcessStart:1248 : internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_UUID=168edaae-e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_NAME=lxcvm1 /bin/sh error receiving signal from container: Input/output error In libvirtd.conf I have: auth_unix_ro = "none" auth_unix_rw = "none" auth_tcp = "none" auth_tls = "none" And in libvirt.conf everything is commented.

Bonjour Guillaume. There's a particular reason to compile libvirt rather than install the package for Ubuntu Server? And, there's a particular reason to use LXC? I'm not an expert, but if you just want to start using KVM and install a VM I can help you through a simpler method. Regards. Javier 2013/4/3 Guillaume Thouvenin <guillaume.thouvenin@polymtl.ca>
Hello,
I'm trying to install and use libvirt 1.0.4 on an Ubuntu 12.04.2. I compiled libvirt by doing:
$ ./configure --with-selinux=no --with-gnutls $ make $ sudo make install
Everything works fine and are installed under /usr/local Then I started the libvirtd manually and try to start a linux container that has the following configuration:
$ virsh -c lxc:/// dumpxml lxcvm1 <domain type='lxc'> <name>lxcvm1</name> <uuid>168edaae-e3b5-2d06-7c65-**9aa444a6f234</uuid> <memory unit='KiB'>2097152</memory> <currentMemory unit='KiB'>2097152</**currentMemory> <vcpu placement='static'>1</vcpu> <os> <type arch='x86_64'>exe</type> <init>/bin/sh</init> </os> <clock offset='utc'/> <on_poweroff>destroy</on_**poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/local/libexec/**libvirt_lxc</emulator> <filesystem type='mount' accessmode='passthrough'> <source dir='/home/thouveng/lxc_dir/**lxcvm1/rootfs'/> <target dir='/'/> </filesystem> <console type='pty'> <target type='lxc' port='0'/> </console> </devices> </domain>
When I start the container I have the following error:
$ virsh -c lxc:/// start lxcvm1 error: Failed to start domain lxcvm1 error: internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=168edaae-e3b5-**2d06-7c65-9aa444a6f234 LIBVIRT_LXC_UUID=168edaae-**e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_NAME=lxcvm1 /bin/sh error receiving signal from container: Input/output error
The libvirtd is started with info option so I can see:
2013-04-03 08:49:20.167+0000: 17046: error : virNetSocketReadWire:1362 : Cannot recv data: Connection reset by peer 2013-04-03 08:49:20.267+0000: 17051: error : virLXCProcessStart:1248 : internal error guest failed to start: PATH=/bin:/sbin TERM=linux container=lxc-libvirt container_uuid=168edaae-e3b5-**2d06-7c65-9aa444a6f234 LIBVIRT_LXC_UUID=168edaae-**e3b5-2d06-7c65-9aa444a6f234 LIBVIRT_LXC_NAME=lxcvm1 /bin/sh error receiving signal from container: Input/output error
In libvirtd.conf I have:
auth_unix_ro = "none" auth_unix_rw = "none" auth_tcp = "none" auth_tls = "none"
And in libvirt.conf everything is commented.
I have this error as normal user (in libvirtd group) and also as root. Any hints to go further in the debugging are welcome.
Regards, Guillaume

Hello Javier, The reason to compile libvirt is that I need a version >= 1.0.1 because there are some features that are not available before this version (see the post of Daniel P.Berrange about "How to give access to /dev/tty"). Currently the version provided by Ubuntu is 0.9.8. And I'm using LXC because I want to start an X server in the container and I also need to have access to the device /dev/nvidiaX. I guess that I could use KVM with PCI-passthrough but unfortunately my BIOS doesn't support IOMMU.
I'm not an expert, but if you just want to start using KVM and install a VM I can help you through a simpler method.
Thanks for your help but I will continue to try LXC ;) Best regards, Guillaume
