Re: [CentOS-virt] Problems with Windows on KVM machine
OK, new info here. Tuning is done, got this on node with Windows 2008 Server. Others with *nix are working good.

1. Try to see the logs on Storage server for more information. What kind of errors you are getting?

Re: [CentOS-virt] Problems with Windows on KVM machine
I'm not an expert on this, but here is what I would try: 1. Are you using the latest virtio drivers on your Windows guest(s)? http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/ 2. Is there any particular reason you use CentOS 6.4 on your storage server? I would update it to CentOS 6.5 so you would have matching Linux kernels on both of your systems.

[CentOS-virt] Problems with Windows on KVM machine
Hello. We've started a virtualisation project and got stuck in one moment. Currently we are using the following: Intel 2312WPQJR as a node Intel R2312GL4GS as a storage with Intel Infiniband 2 ports controller Infiniband Mellanox SwitchX IS5023 for commutation. The nodes run CentOS 6.5 with built-in Infiniband package (Linux v0002 2.6.32-431.el6.x86_64), the storage - CentOS 6.4 also built-in drivers (Linux stor1.colocat.ru 2.6.32-279.el6.x86_64). On the storage is made an array, that is shown in system as /storage/s01. Then it is exported via NFS. The nodes connect to NFS by: /bin/mount -t nfs -o rdma,port=20049,rw,hard,timeo=600,retrans=5,async,nfsvers=3,intr 192.168.1.1:/storage/s01 /home/storage/sata/01 mount shows: 192.168.1.1:/storage/s01 on /home/storage/sata/01 type nfs (rw,rdma,port=20049,hard,timeo=600,retrans=5,nfsvers=3,intr,addr=192.168.1.1) Then we create a virtual machine with virsh with a disk bus virtio. All is OK, until we don't start Windows on KVM. It may work for 2 hours or 2 days, but under heavy load it hangs the mount (i.e. /sata/02 and 03 are accessible, but requesting 01 will result in a total hang of console). This can be beaten only by hardware reset of the node. If we mount without rdma - all is fine. What can we do in such case? If any debugs or info needed - please ask.
