...nts the userland part of the blktap driver. . Virtual Hard Disk (VHD) is a file format standard which maps logical hard disk contents to a physical disk image format, which can then be more efficiently stored in a variety of different storage types, such as file systems or logical volumes. . VHDs are container files storing block metadata alongside a virtual disk's contents, in a single disk image. The metadata enables advanced storage backend capabilities, such as thin provisioning, disk image snapshotting, and coalescing of differencing disks. . Libvhd is a library to access VHD...

...g those steps did not work out to me. I am using XCP 1.6 over, hen hypervisor 4.1.1 on Ubuntu 12.10. And as the management tool, I am using Cloudstack 4.1.1. The error started when I tried to create a template from a VM image, I guess something went wrong at the time that Cloudstack was copying the VHDs. Would you have any ideas in how to work this around? -- Rafael Weingärtner _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

Hi list, I have recently migrated to XCP from Vmware Server 2 and have run into issues importing the VM''s Following citrix''s guide I tried using XenCenter to do the import directly on the vmdk files this resulted in XenCenter logging this error: "Failed to import. ---> System.Exception: Failed to import virtual disk file. ---> System.Xml.XmlException: Root element

...struct was being used to indicate the path. That's natural enough, but that practice is what was dropping the query string. The query string is kept separately from the path. I now concat the query string back onto the URI with a separating '?'. I've successfully mounted remote vhds in Azure with this new code, and the basic set of tests pass. If there's anything else I can do by way of verification, please let me know. -- Gabriel

I see that Microsoft has a utility that (apparently) can read a running system and create an image that can then be imported and run on Virtualbox. https://docs.microsoft.com/en-us/sysinternals/downloads/disk2vhd "You can even have Disk2vhd create the VHDs on local volumes, even ones being converted (though performance is better when the VHD is on a disk different than ones being converted)." Is there anything that does the same thing for Linux, and can image a system like that while it's actually running? -- Can we uninstall 2020 and ins...

I think the way to go is to add an extra parameter to the guestfs_add_dr...

I created a NFS VHD SR(\nfs\xxxx-yyyy-zzzz-wwww) on host “A” and created set of disks(vhds). I de-attached the SR from “A” and attached to host “B”. Host B seeing all the disks. Its working up to that fine. But I again de-attached the SR and attached to host A, it shows no disks in that SR. While reattaching to host “A” it shows the SR existing but after attached nothing comes. If...

...nvolved, but apart from that, I get 930-950Mb/s, which I am happy with. However, as soon as I start testing from a XCP host, the iSCSI performance drops from the 50-55 MB/s in Ubuntu to 25-30 in XCP. What really bugs me, is the VM performance - on a good day, I get 10MB/s writes to the iSCSI root VHDs, with short peaks of 20-25. The performance varies greatly, from those peaks of 20-25 to deep troughs of 2-3MB/s. Writing to an NFS share from a VM is still fine, though - in-VM NFS performance equals that of a "raw" Ubuntu install. Furthermore, I have a few hosts with local SSDs meant f...

...ing the query string to the path is a good idea. For example, we do a minimum of parsing of the URI, and for some protocols (like the "We may have to adjust the path ..." comment says) we adjust path according to the elements in the query string. > I've successfully mounted remote vhds in Azure with this new code, and the > basic set of tests pass.
