Hello, Without using XM, is it safe to write the letter corresponding to the desired sysrq to xenstore in /local/domain/domid/control/sysrq ? Does anything else have to happen? I am working on some backup utilities that utilize the lvm2 library (liblvm2cmd) , libxenctrl and libxenstore. The program will issue a sysrq S to a guest, pause it, take a snapshot then unpause it (all very quickly). An

Hi All, We tested xm block-configure command. Because when the domain image is made, we install it from multiple CDROM. The procedure of the installation is as follows. 1) The HVM domain is started with the CDROM device. 　・configuration file : 　disk = [ ''file:/xen/test/install-test.img,hda,w'',''phy:/dev/cdrom,hdc:cdrom,r'' ] 　boot="d" 2) When

1) Misspelled message ''killing umanaged domain'' (must be killing UNmanaged domain) 2) more serious. I found this message after disappearance of virtual machine created early. I restart XAPI tool stack and machine was killed (not shutdowned, but completely removing). Here log (from machine where domain was resident) Main line in log file I suspect:

Hi, When I tested the xm pause/unpause command, I found poor error messages. The following is the error messages. # xm list Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 492 1 r----- 394.6 vm1 1 512 1 r----- 3.0 # xm pause 0 Error: (22, ''Invalid argument'') # xm pause

Hi, all, When working on adding PM support to xen, we realized that some enhancements are required to suspend/resume domU. Following is some background and thoughts, and welcome on comments. :-) Currently we use a simple approach (pause/unpause) for domU when ready to pull whole platform into a power save state, saying a S3. Because pause/unpause is out of domU''s knowledge, domU

Hi everyone, I''m making a user application that''s going to run in Xen guests (both dom0 and domU) and each instance needs to read values from the VM''s unique space in XenStore. The way I have done it is use the functions defined in <xs.h> using the xs_read function to read a value. In command line I''m able to use the xenstore-read program and simply pass

In the logfile are no informations, in the routed

Hey everyone, I''m trying to write a simple python program in dom0 that registers a watch on the xenstore to determine when a domU has shutdown. Is there a particular token I should use? Looking through the tools/python/xen/*.py code, I''ve come across the ''control/shutdown'' token... seems promising? My code is attached below. As is, if fails to call the

Hi folks, we (the company i am working for) are running several dozens of virtualisation servers using CentOS 6 + Xen4CentOS as the virtualisation infrastructure. With the latest versions of all packages installed [1], we see failures in live-migration of stock-CentOS6 HVM guests, leaving a "Domain-unnamed" on the source host, while the migrated guest runs fine on the target host.
