I tried to create a domain with drbd based disk as the backend "drbd:<resourcename>,..," and I get a "unknown disk type" error. I can spin out a patch if needed, but just wanted to know apriori if this was left out for any specific reason. shriram _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I noticed recently that there is no real easy way to get the kernel driver for blktap working in mainline. I''ve pulled down the source from Daniel Stodden''s linux git tree on xensource, but it looks like it''s for debian and I''m running Fedora 14, so I''m trying to sort it out. I run the 3.1.x kernel and don''t want to go back to the 2.6.32 that

...b) Libnl3 is not available on NetBSD. Nor is it available on CentOS (Linux). So I have made network buffering support an optional feature so that it can be disabled if desired. c) NetBSD does not have libnl3. So I have put the setup script under tools/hotplug/Linux folder. thanks shriram

Hi, I am trying to understand and change the network buffering that is being used by Remus, the HA solution present in Xen. From what i understood from reading the code, Remus calls the postsuspend method of the BufferedNIC after it suspends the domain that sends TC_PLUG_CHECKPOINT message and start the buffering and then calls the commit method of BufferedNIC after it gets the acknowledgement

Hi, I''m doing my master research and I need to adapt remus code. Now... I wanna get the checkpoint size (memory + disk) on each period. Does someone know what function does this? I think some *fd *object''s function in remus code could just get the memory size. Does someone help me? Thanks _______________________________________________ Xen-devel mailing list

...rubx64.efi Where should I put the xen efi ? I tried creating a efi/EFI/xen/xen-4.2-unstable.efi and added it as a boot option using efibootmgr. All I get in that case is a blank screen. I had to go into the UEFI bios menu to delete that option in order to boot the system via the usual grub. Thanks Shriram

Hi, The following patch series fixes hangup after creating checkpoint on Xen. The Linux Xen guest can be saved the state to restore later, and also created snapshot like checkpoint via the hypervisor. But, when the snapshot is created for the PV guest, it will hangup. We added ''PMSG_CANCEL'' message and ''cancel'' handler in dev_pm_ops struct in the pm-linux

Hi All, I want to test REMUS over XEN, I would like to know the basic steps to be followed .

I noted a possible problem restoring a machine. In xc_domain_restore (xc_domain_restore.c) if it''s not the last checkpoint we set O_NONBLOCK flag (search for fcntl) that we can call pagebuf_get or just load other pages (see following "goto loadpages;" line). Now we could ending up calling xc_tmem_restore/xc_tmem_restore_extra (xc_tmem.c) which call read_extract (xc_private.c)

Dear List, i''m experimenting with remus with the following setup. dom0: - Debian Squeeze - Jeremy''s 2.6.38.48 kernel - xen 4.1.2 recompiled from sid - DRBD for block device backend domU - Debian Squeeze Remus is working fine unless i try to give more than 1 core to the domU. Here''s the error from remus when i''m trying to enable it for an SMP domU:

Hello, I have been playing around with Remus on Xen 4.0.1, attempting to fail-over for an HVM domU. I''ve run into some problems that I think could be related to tapdisk2 and its interaction with how one sets up Remus disk replication in the domU config file. A few things I''ve noticed: -The tap:remus:backupHostIP:port|aio:imagePath notation does not work for me, although this

Hi all, as promised I run some simple benchmarks using tapdisk2 and the new qemu as disk backends. If you are in a hurry skip to the last section to see the test results. SOFTWARE REQUIREMENTS --------------------- In order to reproduce these results you need to use the new qemu with linux aio and O_DIRECT as disk backend: - apply the libxl patches that Anthony sent to the list a little while

Hey, There has been some discussion about EFI and SecureBoot and such. Most of the time I get questions in the form of "How do I get Fedora 17 with Xen to do EFI", I am going to concentrate on Fedora, but I think this applies to other distros too. From my reading (I hadn't actually tried EFI yet), there are two ways to bootup a system: - Using grub2.efi. Grub2 does the EFI API
