Hi, This is Arpita. I am using Libvirt API in the Windows Vista system.VMware is installed over there.I have installed Libvirt and Python 2.6 in the Windows Vista system andhave written a small test file in Python. Here is the code: import libvirt* * import sys conn = libvirt.openReadOnly(None) if conn == None: print *'Failed to open connection to the hypervisor' * sys.exit(1)

Hi all, I've succeed to do live migration between two PCs. However, I found I could not connect the VM by host IP from a remote PC before migration and can only connect it from host PC. If I appended the VM with the following line at the end of the xml file: <listen type='address' address=host_IP port='PORT'> I can connect the VM via VNCVIEWER with host_IP:PORT.

I have a python script that monitors the guest VMs on a servers running Xen, but the script doesn't work properly on a server I just built with KVM. The script runs as a non-root user (same on all servers) and simply gathers some details on the status and names of the domains running on the host. The Xen and KVM servers are running CentOS 5.4 x86_64 and are using the same version of

Well, not that remote. I'm trying to get it working from my laptop to an ancient workstation behind me I use for testing. I appear to get the connection okay. virt-manager --connect qemu+ssh://root@<host_ip>/system I can click on the entry on the panel that comes up and see facts about the remote machine. I then tried the "Create a new virtual machine" item on the tool

Hi, I have a code : import libvirt con = libvirt.openReadOnly(None) print con.listDomainsID() When i run the above code using root i get the proper output... but when i use non-root user it givers be a empty list [ ] If i change the 2nd line to con = libvirt.open(qemu:///system) It works. I am using RHEL 6.1 with default kvm and libvirt. unix_sock_group = "virt" in

I am running Xen on a RHEL4 dom0 and have two RHEL4 domU''s. The domU''s are both running Oracle 10g R2 database. I want to connect to these databases from another computer. Xen is set up with NAT network and all dom''s have access to the internet and they can ping eachother so the network is up and running. My problem is that I cannot connect to the different oracle

Hi, I am relatively new to xen and have the following question: Can a domain be live migrated to a different domain on the same system? Eg: if i have a domain VM1 and i want to migrate it and run it as VM2.

Hello, We are trying to use 'PXELINUX' for network boot with root file system on ramdisk, the kernel image vmlinuz and compressed root file system rootfs.img.gz are both present in /tftpboot directory PXELINUX client (pxelinux.0) requests and gets the config file AC134D6D from the TFTP server (which supports tsize option) contents are as follows timeout 10 prompt 1 label linux-new

Hello, Does PXELINUX support tftp BLOCK-SIZE option? If so, what would be the maximum BLOCK-SIZE that can be used for the transfer? The RFC says that the range can be [8 - 65536]. Thanks, Sowmya

HI, I am using ubuntu host machine and KVM is present as guest in that machine.Two virtual machines are there.I am using Python binding to query on the hypervisor and extract the VM related information. Here is my simple code: #!/*usr*/local/bin/*python * import libvirt import sys conn = libvirt.openReadOnly(None) if conn == None: print *'Failed to open connection to the

Hi Harish, I believe the proper establishment of a connection should be done by libvirt.open() or libvirt.openAuth() or libvirt.openReadOnly(). All of them will return a functional virConnect instance. I'm not sure this segfault is worth to fix since instantiate a virConnect directly is not an expected usage. Hope this information will help you. Best Regards, Hao Liu +86-010-62608262

Hi, 1) From the code it appears that there is no common entry/exit point for the hypervisor calls. Wanted to confirm if this is right? 2) Also is there a per-domain flag to indicate that the hypervisor call is in progress in a particular domain?

Just in case anyone is using Blockhosts (http://www.aczoom.com/blockhosts/) with their Linux servers and Asterisk here are the rules necessary to block invalid users: "asterisk-NoPeer": r'Registration from .* failed for \'{HOST_IP}\' - No matching peer found', "asterisk-NoAuth": r'Registration from .* failed for \'{HOST_IP}\' - Username/auth name

Hi, I am doing some domain resource monitoring work. I use cat /dev/urandom | md5sum to simulate vCPU load and write a script to calculate vCPU utilization. It seems all good at the beginning. After I abort the ``cat ... md5sum`` command in domain, I see some strange data as below: CPU time: 8410960000000 CPU util: 99.8410609331% CPU time: 8411970000000 CPU util: 100.843672381% CPU time:

I was getting vCPU use time outside of guest with libvirt-python API, and them calculate utilization with (cpuTime2 - cpuTime1) / (t2 - t1). I was not doing this inside the guest os. 2015-07-24 15:09 GMT+08:00 2020human <human2020@qq.com>: > You calculate is vCPU use time not utilization。 > > use_time/total_cpu_time is utilization。 > > total_cpu_time=`cat /proc/stat |sed -n

Hi I have a linux box which has CentOS running in it. I logged into the box using root and wrote a script in the /home/proc_threads directory. saved the file and quit. I changed the file permissions such that any user could execute it using the "chmod 777 filename" command. When i log out and log in as a non-root user i was not able to execute the script though. Could some one

Thanks Dominique & Daniel. Looks like i need to upgrade my VMs kernel to make it aware of virtio. Found this information from this link: http://wiki.libvirt.org/page/Virtio#Disk_.28block.29_device_driver I tried without upgrading the Kernel and as soon as i start my VM it got into Kernel Panic. I will try using virtio after upgrading my VMs kernel. Thanks for all the responses and
