It was resolved by re-installing the KVM host with CentOS 6.0, unfortunately there is not "official" CentOS 5.6 -> CentOS 6.0 upgrade path.

Hi All,

I'm running KVM host on CentOS 5.6 x64, all of my guests are CO 5.6 x64 as well. I create / run VMs via libvirt.

Here are the packages I have:

# rpm -qa | egrep "kvm|virt" kvm-83-224.el5.centos python-virtinst-0.400.3-11.el5 kvm-qemu-img-83-224.el5.centos kmod-kvm-83-224.el5.centos libvirt-python-0.8.2-15.el5 etherboot-zroms-kvm-5.4.4-13.el5.centos libvirt-0.8.2-15.el5 libvirt-devel-0.8.2-15.el5

The problem:

I attached an iSCSI LUN (netapp appliance) to a guest and everything work fine with iscsi-initiator-utils-6.2.0.872-6.el5: LUN discovery, attaching to the host etc. After that I'm trying to copy ~ 140Gb of data to that LUN via scp from another server in the network and the VM crashes after ~ 1 hour of copying .. Nothing in the VM / KVM host logs importunately.

Who has / had similar issues with iSCSI LUNs being connected to a guest?

Thanks, Vladimir
